Indra, a Hindu god name. His titles include "King of the Gods", "King of the Universe", "Generous", "Compassionate", "Drinker of Sumo Wine", "Holding Vajra pestle", "Ruler", "Killer of Fulidor", "Son of Mighty", "Marshal of Moridor's Guard", "Friend", "Giver", and so on. Indra was brought from ancient Iran to India by the Aryan people and later absorbed by Buddhism. In the Chinese translation of Buddhist scriptures, it is called "Heaven Emperor", "Heaven Emperor Interpretation", "Heaven Emperor Interpretation", or "Emperor Interpretation". In Hinduism, he is the head of Sudarsana and is highly revered. Described as a tea brown color throughout the body, capable of changing shapes; Eating Sumo wine is also known as "those who drink Sumo wine". His greatest achievement was to kill the snake demon Vrtra, split mountains to divert water, and was awarded the titles of "Killer of Vrtra" and "Winner in the Water"; He also conquered many castles, including 99 belonging to Friedo, earning him the title of "Castle Destroyer". Originally the god of thunderstorms, he later developed into the god of war, holding a diamond pestle, hence the name "holding a diamond pestle". Its weapons include hooks and nets, claiming to have conquered the indigenous inhabitants of India, the Dasha people. As the protection god of the clan, he won the battle for dominance with the protection god of another clan, Varuna. Later, the two clans united, so he was called "Indra Varuna". Later, Varuna gradually declined, and Indra gained complete dominance and was honored as the "king of the world". His hymns account for a quarter of the entire book of the Rigveda. However, with Brahma becoming the creator and founder, and the role of Vishnu and Shiva increasing dramatically, Indra is still regarded as the god king and the ruler of the heaven, but in fact it is finally in a subordinate position. He often becomes the object of ridicule, repeatedly insulted by immortals, hermits, and monsters, relying on the help of other gods to maintain his position in the heavenly realm.

Indra is the god of war, the embodiment of battle. He fought against the gods, and they were afraid of him. He participated in countless battles against demons and non Aryan gods, and conquered 99 camps belonging to the snake demon Fridor, earning him the title of "Castle Destroyer". Both sides prayed to Indra for victory during the war. Indra's military exploits were also explained from the perspective of the origin of the universe, saying that he gave birth to the sun, the sky, and the morning glow. He consolidated the position of the sun and drove the sun to walk (his eyes were the sun). He fought against Frodo in order to capture the sun. He also splits mountains to divert water, hence he is also known as the "winner in the water". His victory over Frodo meant that positive factors in the universe had overcome negative chaotic states. The result of victory is the establishment of a vast Vedic world.
Indra is also associated with harvest, prosperity, longevity and male power. His attitude towards people, especially Aryan people, was kind and friendly, and he was ready to help. He appeared multiple times as a singer, drummer, and dancer. In the Rigveda, it is said that he has been transformed into other objects multiple times. Indra belongs to a highly personified God, who has detailed descriptions of his appearance, clothes, voice, body, temperament, wisdom, etc. His mother didn't want him to be born. His mother's name is not mentioned in the Rigveda. In Atharvaveda, his mother is called Igashudoga, equal to the night god Radori. In the epic, Indra is said to be the seventh son of Aditi. In Rigveda, he is called the fourth son of Aditi. His father was sometimes called Dyaus, sometimes called Tvashtr or the birth master. In the Sanskrit, it is often said that he is the youngest son of the Creator, and sometimes it is said that he was created by the gods. Indra's wife was sometimes Indra, sometimes Shezhi or Bulumi. In Atharvaveda, his wife is Borasakha and Shina. His twin brother is Agni or Samadhi. He was associated with the gods of Morudo Ashvins, Ushas Vador, Vauye, and Adityas. This gives him a special position at least in the Vedic stage. He has a new connection in the epic. In the post Vedic stage, the significance of Indra has obviously declined. Some of his functions have undergone changes. Especially since his creation role was completely excluded, it strengthened his role as a military leader. In the epic, he is a god associated with rain and harvest, and is very similar to the rain god Pojahnya, to the point of equality. The name of Indra was also called in the ceremony of praying for rain. His becoming the Protector of the World was also a later event. Brahma bestowed him with dominion over the East. His god is guarding this side like Aravado. The gods of Adityas, Absaloth, Gandava and Siddhartha were his assistants.

In Mahabharata, the kingdom of Indra and his paradise with 1000 gates are described in detail. At the same time, he also lost his omnipotent nature. He has been defeated by immortals and even demons more than once. Therefore, his reverence was questioned. This sign is already present in the Rigveda. There are many myths related to Indra, and the central story is his struggle with Frito. He defeated Fredo with the steel pestle that Tvashtr made for him. Water that had been imprisoned by Frodo flowed out of his limbs. According to another legend, Indra not only liberated the water, but also liberated the cattle locked in the cave (see "Brahma" article). He also found light and dawn from the cave. There are many similar myths in the Rigveda. After the Vedic period, there were significant changes in the old myths. For example, the myth of the battle against Frodo excludes the origin of the universe from the epic and introduces new characters. New themes and details have emerged. For example, Indra sent the fairies of Absaloth to seduce three monsters, Vishurupo, and finally cut off his three. Indra was swallowed by Frito, and he opened his stomach and walked out of it (Bhagavan Puranas). Indra sent Morudo or Vaya to inquire about the situation. Indra dismembered Frito into two parts, one divided into the moon and the other into the belly of animals.
In Sanskrit books and epics, Indra's battle myth stories were further processed and developed. Indra killed the monster Bulumi, and his daughter Shezhi was rescued by Indra and became Indra's wife. Indra defeated the giant Zhanba. Indra also seduced Lucie, the wife of the immortal Tiva Shoumo, who was rejected. He lured the wife of the hermit Jortama, Aholiya, and was cursed by Jortama for losing her testicles. (Another said that the immortal cursed Indra, which made him bear a thousand marks that looked like female genitals, and then turned into a thousand eyes, so it was also called "thousand eyes") [2] Indra (one said that it was Brahma) returned the kidnapped Indra to her husband and prayed to the Lord. After Indra was expelled, Nahusha, the king of the Lunar dynasty, occupied the throne of Indra in the sky, and was given the wife of Indra, Sheyan. Later, because the sand guard arrogantly asked the immortals to raise a sedan chair for him in the air, he was overthrown to the ground and turned into a snake, and Indra regained the throne (Mahabharata V, VIII). Indra was jealous that Ashvins could get Sumo wine from the immortal Bili Quchi Yeva, so he wanted to kill Bili Quchi Yeva. The latter created the monster Motha (meaning "drunken") to punish Indra. Indra. Bi Li Qu Chiyevna forgives Indra and dismembers the monster. Indra used clouds and rain to help him and his children escape the shooting of the sun. Indra mocked a few dwarf philosophers (fingers as big) Brahjiriya, and they predicted that Indra would be defeated by the golden winged bird Garuda. Later, Garuda really took the tableware containing the fairy dew from Indra.

When stirring the Sea of Milk, Indra got the god horse Wujatsu Nirvana, the god image Aravado and the god tree Bodhidhartha. (Mahabharata I, Vishnu Puranas I). Indra grew a thousand eyes (ibid. XIV) in order to see the peerless beauty tilutomo (q.v.). Indra became a peacock because he was afraid of meeting the King of Raksha. Indra was captured in the struggle with Mikanatta (Indra Qi), the son of Rabona, and was escorted to Lenga Island. Brahma and the gods personally came forward to persuade Mikanatha to release Indra. He sent the beautiful Abu Sharoth Minaga to seduce the Vishvamitra and destroy his asceticism, because his asceticism might take away his power. Indra was afraid that Sakhala's son would be as powerful as him, so he stole their horse. In order to test the piety of the king Ushnara, Indra turned into an eagle and Agni turned into a dove, making it look like an eagle chasing a dove. In order to save the dove's life, Ushnaro cut a piece of meat from himself and fed it to the eagle. Indra believed in the piety of Ushnara and predicted that he would gain eternal glory (Mahabharata III).
Indra destroyed the sons of Titi, Dietier, in the battle. Then Titi asked her husband to let her have another son to avenge Indra. As a result, they gave birth to their son King Kong, defeated Indra and bound him to his parents. Brahma came forward to save Indra. In the absence of the Vajra, Indra turned into a monkey and a snake, and finally robbed the Vajra's wife, who was later recaptured by the Vajra. In order to seek revenge for the second time, King Kong and his wife gave birth to the son Doraga. He led the Ashura to declare war on Indra and defeated the gods led by Indra. The gods sought help from Brahman. Brahma suggested that Shiva marry Uma. Only the children they give birth to can defeat Doraga. Based on this story, Kalita wrote the long poem "The Birth of Kumaras". In many stories, Indra is closely connected with Shiva and Vishnu [1].

Vedic Age
In Vedic mythology, Indra is the god of storms, waving the weapon of thunder and lightning (Vajra) held by his right hand. He is like an Aryan warrior king, fair skinned with a hint of red or gold, riding a horse or driving a golden chariot pulled by two yellow brown horses with flying manes and tails. He has a wild personality and enjoys drinking Sumo - a intoxicating beverage that can give him strength. He is a strong defender of the gods and humanity, resisting the demon Frodo, who represents the harsh aspects of nature, especially drought. As a rain sower in India's arid countryside, Indra is the most frequently prayed god among the Vedic gods, and it is also the god centered in most myths. The stories about his birth and his achievements when he was a child clearly showed this belief, and explained the competition between Indra and Varuna in the language of mythology (which can be understood as the competition between the Brahmin priestly caste and the Kshatriya warrior caste). He gradually arrogated many functions and merits of Varuna, and finally replaced Varuna as the leader of the gods.
Indra's mother, Prithvi, concealed the birth of her son. When Indra was born, human beings were praying to the gods to rescue them and expel the devil Frito. Frito imprisoned the cloud cow, so that human beings fell into famine due to drought. Indra saw this and took the sumo they had dedicated to the gods from Tvashtr, and drank a huge amount of sumo equivalent to 100 cows. After drinking Sumo, his body was huge and filled with two realms. Indra grabbed the thunder pestle that belonged to his father and set out in a chariot with two horses. The retinue followed him to fight with Frito. When Indra came near, Frito roared loudly, the sky shook, and the gods fled. Prithvi was more and more worried about his son, but Indra was inspired by a large number of Sumo and human priests' hymns he drank. Sacrifice also strengthened his strength, and more importantly, he mastered thunder and lightning (Vajra). He stirred up a storm and captured 00 castles in Friedo, then faced the demon himself. Although Frito thought he was invulnerable, Indra soon found his weakness and knocked him down with a thunder pestle. After Yunniu was released, torrential rain immediately poured down on the ground. According to some legends, Indra repeats this heroic act every summer at the end of the dry season to rebuild his prestige in the minds of mortals and gods.
Indra almost kept hearing the praises of the priests and his fellow gods. As soon as he was born, he took the lead as a rain sower. In this action, he replaced Varuna -- although it should be admitted that he needs to pay more efforts to sow rain than Varuna. There is an explanation that this transfer of power involves the competition between the Brahmin priests and the Kshatriya warriors. Then Indra attacked his father (sometimes referred to as Varuna). He grabbed his father's ankle, knocked him down and killed him. His mother's lamentation was of no help. Because he killed Dyaus, Indra established his independent status and lofty image. His father killing established his right of inheritance to his father, just as he defeated Fredo to establish his highest position and right of inheritance to Varuna to some extent.

Because of Indra's first heroic act, he became the king of the three realms, gained strength and the power of Sumo, and gave them to others. Therefore, he represents the power of personal interference and the activities of warriors, while Varuna represents the inevitability of the order of the universe. Varuna's power is based on law and magic, while Indra's power is maintained by the sacrifice of mortals. Humans can't understand Varuna's way, but they can influence and even guide God to bless continuously if they turn to Indra.
Indra fought tirelessly against demons. He has conquered Fulido multiple times. It was under the leadership of Phrido that the Danavas were able to disrupt the permanent balance established between gods and demons, Devas and Asura, good and evil, and light and darkness. Indra also forced Dhanava to flee to the abyss of the sea. He also protected people and animals and shattered the conspiracy of other demons. As a rainsower, Indra has some kind of "fertility god" In the struggle with the gods, the demons once realized that the gods gained powerful power from human sacrifices, so they decided to use poison and witchcraft spells to pollute the plants consumed by humans and animals, thereby weakening their power. They finally succeeded, and people stopped eating, while animals no longer ate grass. Hunger brought them to the brink of death. The gods held sacrifices to eliminate the poison from the plants. A grand celebration was held to celebrate this victory The sacrificial offerings at the ceremony are made from the first batch of plants grown after removing toxins. There is controversy among the gods over who will accept the sacrifice. Later, it was decided to solve this problem with a race. Indra won the contest with Agni, and since then Indra has been regarded as the source of reproduction.
Indra gradually replaced some other functions of Varuna, and his role as the god of reproduction expanded to a new role as the god of creation. Like other creative gods in India, Indra did not construct the universe from nothingness, but rearranged it after occupying the universe. Like Varuna, he used the sun as an instrument to measure space; The six vast spaces he marked include everything that exists. Then, he began to build the universe like a house: he erected four corner pillars and built a world wall between them; He covered the roof with a cloudy sky. This house has two gates, and the east gate opens wide every morning to welcome the sun; The western doors are slightly opened at dusk every day so that Indra can throw the sun into the darkness around. When the gods come to share sacrifices and wine offerings, they also walk through these doors. Indra supports the heavens, maintains the three realms of heaven, space and earth, holds up and spreads out the earth, so as to maintain the universe he created. He is also the main source of rivers.

Sumo strengthened his physical strength, and Indra had the power to adjust the heavens, the sun, the moon and the seasons. His fondness and dependence on Suma were increasingly detailed in the Vedas, but soon this point became completely seen as a weakness. In the Vedic era, Indra was the largest god among the gods, even though it was not as awe inspiring as Varuna produced in his glorious era before him. Later in the Vedic era, Indra became a more pampered, reclusive monarch. He reigned in his kingdom of heaven, flanked by his wife Indrony and his counsellors Vasus. Although he was still accompanied by a hunting dog (the dog later became an unclean animal), he gave up his horse and became a huge white elephant named Arrovador, with four ivory tusks. Its huge snow-white body was compared to the Jirosa Mountain (Kai Mount Rath Mountain), where Shiva's heavenly kingdom is located. [6]
Hindu era
In Hindu mythology, Indra is still the king of the gods, although he is powerless to dominate or influence the combination of Brahma, Vishnu and Shiva. His functions are roughly the same as those of the Vedic era, although many aspects of his character are more emphasized, especially those undesirable aspects, such as his hobby for Suma, his sin of killing Brahmin, his frivolity, and his incompetence in the face of the immortal curse, which sometimes makes him defeated by demons.
As the god of storms, Indra is still a terrible image, throwing lightning and thunder, and using the rainbow as a bow, but he is no longer completely the god of war: as the ruler of the air and the guardian god of the east of the world, he exercises his rights in a more noble way. He rode on the giant white elephant Aravado instead of riding on a chariot or riding the divine horse Ujrashtra Prabhasa. His strength relies on monarchy rather than force. Sometimes it is even said that Indra is just a title rather than a single god. This title is awarded to the most meritorious god or mortal every 3600 years. However, "merit" can include only 100 sacrifices. According to this, the status of Indra was obtained through fraud. It is said that he took offerings from some mortals who were essential for holding ceremonies, and even sent enchanting fairies to deceive those mortals who accumulated merit through hard work.

Indra lives in the kingdom of heaven on Mount Meru. The capital is called Amorapoti. His kingdom of heaven is still a magnificent residence, although at this time Indra and his wife Indrani can only dominate the souls of some small gods and those virtuous people who have been rewarded by the reincarnation from the earth temporarily.
In the Vedic mythology of Indra's war with Friedo, Vishnu was a young assistant of Indra, so he had the title of "little Indra". However, Vishnu's role gradually increased in later myths and legends, surpassing Indra, so he also had the title of "big Indra". According to the "Forest Chapter" in Mahabharata, Indra was very afraid of Indra, who swallowed Indra into his belly, and then failed until Vishnu came to help fight, and then turned defeat into victory. Vishnu gave the god the power of his spirit, helping him to subdue him. He also said that Vishnu infiltrated the Vajra pestle of Indra, which greatly increased its power. He also said that Indra broke the belly of Frito himself and turned the corner (Bhagavan Puranas); Indra covered his weapons with foam; Send Mo Luduo ("Zhegu Sanskrit") or Fa You ("Baidao Sanskrit") to visit; Indudo divided Friedo into two parts: one became the moon, and the other became the belly of all living things; He also said that Frito and all Brahmin were expelled because of the killing of both by Buddha. [9-10]
Indra is still fighting against demons, but he can't always win. This is because according to the new belief, power is not obtained by drinking Sumo. The demons always refuse to drink Sumo, but gain power by offering sacrifices or practicing asceticism to please the three highest gods. Evil spirits are involved in this way, partly because Indra was implicated in the old crime of killing Brahmin (killing Frito is also considered a sin at this time), This accusation haunts him in a personified form. Indra had to hide in order to escape the accusation, and finally got rid of it only because he diligently practiced asceticism.
During this period of time, Indra was at the mercy of others. One king, Nahuosha, gained hegemony over the three realms, but he didn't succeed because of the curse of the Agastya, which saved Indra's reputation. The Agastya drove the carriage of Mohuosha to the heaven of Indra, because the mohuosha accidentally touched his foot, which made him angry. The Agastya cursed the sofa guard and made him fall into the world again as a snake.

Another king, Boli, also gained control over the three realms by pleasing the great god. He defeated Indra and expelled him from the heaven. Without the intervention of Vishnu, who was a dwarf, Boli would not be driven out of the heaven and earth.
The King of Lenga, Lobona, gained great power because of his Brahmin origin and religious practice, and he also made Indra sweep the country. When Robona's army attacked Indra's kingdom of heaven, the king of the gods found that he could never defend it. He was captured by the son of Robona, who had received the blessing of Shiva to the invisible Michanata. Mikanatha tied up Indra and took him to Lenga Island as a hostage. Indra and other captured gods were forced to serve him as slaves. Agni cooks for Lobona, Varuna draws water for him, Kubera provides money for him, and Varyo cleans his palace. Brahma had to lead other gods to Lingha Island to ask for their release. Brahma granted the title of "Indra Jai" ("Indra's conqueror") to Mikanato, who accepted the title. Since then, he became famous for it, but offered a higher ransom: he asked to live forever. Because of Indra's poor situation, Brahma finally had to agree to his request.
Another time, Indra gave a small elephant a wreath of flowers presented to him by the Durvasa, Shiva's incarnation. Because of this contempt, Indra was cursed: his supreme rule over the three realms would be overthrown. The curse came true when Indra and other gods became weak and defeated by Dedijah, led by Raj, Dedijah's partner. Indra was expelled from his kingdom of heaven. The god who had been able to dominate the offerings for 100 sacrifices had to take turns to beg for some sacrificial butter from other gods. However, due to Daitye's own fault, they only enjoyed a short-lived carnival. When they are proud, they neglect to fulfill their duties, and the world goes downhill, with the dew no longer present. Therefore, on the advice of Vishnu, Indra suggested to Datiya that the gods and Asura should work together to remedy the matter. They agreed, resulting in the famous stir milk sea. During the stirring of the milk sea, Asura was deceived into taking the agreed portion of the nectar, thus losing the power to resist the newly strengthened gods. Thus Indra could only restore his kingdom of heaven by deception.

According to another version of the same story, in the ongoing war between God (Deva) and Asura, Brahma bestowed upon Raj the ability to command a victorious army. At first, Asura sought the help of Roji, but was rejected because they were unwilling to promise to make him king. The gods lacked trust in their leaders. If Raj could lead them to victory, they would accept him. So Ashura was defeated and Zhihu Indra was forced to step down from the throne. But Raj did not stay in the kingdom of heaven. He let Indra stay there as his regent. Indra rebuilt his rule by trickery. After Raji died, Indra refused to recognize the inheritance rights of his 500 sons. These sons tried to seize the inheritance right, but were defeated by the Brihaspati, who made them fall into chaos and finally perish.
The story of Indra's indulging in wine and sex was told in great detail in later times. His hobby, Suma, was once recognized as a source of strength in the Vedic era, but at this time it made him weak and debauched, as alcoholic beverages were criticized and prohibited for mortals. Examples of Indra's sexual morality are often cited to defend the negligence of others.
It is said that Indra chose Indra as his wife because of her sensual charm, and Indra committed a double crime to win her. Indrani was the daughter of Asura Bulumi. When Bulumi found that Indra had raped his daughter, he was about to curse Indra, and Indra killed him first. Although Indra has always been Indra's chief queen, Indra has already had numerous affairs, and the goal is usually to marry women.
One of the most famous love affairs was Indra and Aholiya, the wife of her teacher, Qiaotama Immortal. Aholiya was the first woman created by Brahman, with exceptional beauty. One day when Immortal Jortamo left his seclusion, Indra took the opportunity to come in. Aholiya was moved by his sweet words. When she was about to yield, Immortal Jortamo returned home and found the man and woman together. He immediately cursed Indra and left 1000 jonni (vulva) marks on Indra. Later, however, when he realized that Indra's crime was only an intention rather than a crime already committed, the Immortal Jortama pardoned Indra and changed the "1000 marks of shame" into 1000 eyes. However, Indra could not restrain his desire to possess Aholiya. With the connivance of Sumo, the moon god who turned into a rooster and crowed in the middle of the night, Indra tried to lead the immortal Jotamo out of the house to do morning prayers. Then he turned into the immortal and replaced him by Aholiya. This time the Immortal Jortama came back too late, and he cursed his wife and Indra. Aholiya was turned into a stone, and only after Vishnu kicked her when she was incarnated as Rama could she recover. Indra was cursed and became a eunuch, but due to the intervention of the gods, he was forgiven after a sacrifice. However, Indra was punished, and later he suffered humiliation under Ravana and Indra Raji [7].

According to the narrative poem, Indra is mainly characterized by the Vajra pestle, the divine chariot, and the invincible spear "Amoka" (which can return after killing hundreds of enemies), the god snail "Devadatta" (by which Indra conquered all realms). It is said that the Vajra pestle is made by Tvashtr with the bones of the immortal Tuo. It is the favorite weapon of the king of gods and becomes a symbol of sharpness, quickness, accuracy and victory over the enemy. Indra's divine chariot was drawn by the fiery steed, shining like a shooting star across the sky, and like a fire flying high in the sky; Its sound is like thunder. He also said that Indra had lent this cart to Ajna (Mahabharata) and Rama (Ramayana) to help them achieve war achievements. In the narrative poem, it was mentioned that Indra was the god of protecting the world, and the god image "Aravado" accompanied it [11].

According to the narrative poem, there are several theories about the composition of the world: (1) divided into two parts, which is obviously relatively ancient; (2) Divided into three parts, similar to what is said in the Vedas, commonly found in narrative poetry; (3) The heaven is opposite to the earth, and the heaven is divided into several layers, such as the Great Brahma realm, Vishnu realm, and the realm of the gods. This theory corresponds to Buddhism, and belongs to the later period of narrative poetry. According to the narrative poem, Indra lived in the so-called "third day" of heaven where the gods lived. It is said that "the realm of Indra" is located above the realm of the righteous. The sky where Indra is located is called "Amoravati", and there are also forests called "Nantana" and "Ganda Motana"; These situations are beyond the reach of mortals. Two forests are located on the golden summit of Mount Milu. The capital of Indra, Amorapoti, is full of exotic flowers and plants, and gemstones; There is a scene of joy here, neither sorrow nor sorrow. Indra's followers are numerous and extremely numerous. It is said that when Azhouna arrived at the heaven, the gods, all Qiantapa and Zuling greeted Indra's heaven, and the Shantanu was among them. Azuna witnessed Rudra, Bosu, Satya, Morudo, Adido and Ashvins. Those living in the heavenly realm treated Azuna with courtesy and gifted him with magical weapons. According to the narrative poem, Indra and the Goddess of Heaven lived together on the third day; He once rode in a shining divine chariot to meet with the brothers of the Pandu tribe, with all the Gandava and Avasara gathered around him. All the Qiantava and Abasaolu offered songs and dances to the leaders of the gods. They are not only associated with the god of wealth, Kubera, but also serve the only master in the world, Indra. Zomorudo is regarded as Indra's effective helper in the fierce battle, and is also called "the master of Morudo" because of Indra. According to the narrative poem, Indra is regarded as the head of the Thirty Three Gods or the Thirty Three Gods, "the Thirty Three Gods follow the Emperor to interpret heaven". In the Vedas, there is a saying of thirty-three gods. In narrative poetry, the "thirty three gods" become synonymous with the "gods" or are considered synonymous with the "immortals". They worshipped Indra and worked for the God, and Indra became their master. The third day where Indra lived with the gods was described as a blessed place for the righteous after their death. Those who offer sacrifices devoutly, those who die bravely in battle, and those who practice asceticism and have achieved great virtue can ascend to this celestial realm after death. Women who are obedient and loyal to their husbands can also enjoy this happiness.

Ashura has evolved from the primitive god of the Indo Iraqi period to the demon of the Indian Aryan period, probably related to the rise of the air god Indra. The opposite of Indra, Frito, is often confused with the demon Daxiu in Rigveda. The latter is the demonized image of Indian indigenous people (Daxiu Dasyu, a branch of ancient Dravidian peoples who fought against Aryan invasion [15]), and Frito is regarded as the symbol of demonized non Aryan tribal leaders. Indra's act of cutting off Frito is a metaphorical expression of Indian Aryan people's conquest of local natives. Adityas (Zhong'ashura), led by Varuna, could not defeat Fulido, and could not finish the task of subduing the natives. So Varuna, the original clan ancestor god, had to give up the position of "overlord" and replace it with Indra, the new clan ancestor god. Since then, the general trend of Asura has gone, and the Deva God led by Indra has become increasingly powerful, becoming the main object of people's praise. The usurped Asura was unwilling to fail and always wanted to restore his former hegemonic position, which evolved into a struggle between Asura and Deva. In fact, this is a reflection of the intensification of internal contradictions among Indian Aryan people and the confrontation between various clans and tribes. As time goes by, the traditional concept of god devil confrontation has formed [14].

Indra Festival is an eight day festival in Nepal, which falls in early September of the Gregorian calendar every year. At that time, Nepal's 5-month rainy season was about to end, and a 7-month dry season was about to arrive. The Nepali language language of this festival is "Indra Jatra". "Indra" is the name of Indra, the ruler of the heaven. It is the king of the gods, and is specifically in charge of clouds and rain. 'Jatra' means parade. Therefore, many people regard Indra Day as a day of praying for rain and thanksgiving in this agricultural country. In Kathmandu Valley, the political, economic and cultural center of Nepal, it is a day for gods and people, the dead and the living, rulers and people to celebrate together. It is also a festival shared by Hindus and Buddhists, the two most influential religious groups in Nepal. Duba Square in Kathmandu is the main place to celebrate Indra Festival. On the first morning of the official start of the festival, a grand ceremony will be held to erect the tree trunk. At the top of a pine tree pole about ten meters high, there is a small red flag in a bar shape. At the beginning of the ceremony, dozens of men pulled thick ropes in one direction, and amidst the noisy cheers, the tall tree trunk slowly stood up. The square also began to boil. The sound of drums seemed to overwhelm the cheers of the people, while soldiers in traditional attire fired their old rifles into the air. The tree trunk stood up and the red flag flew. People thought: Indra came to Kathmandu Valley, where flowers are in full bloom. In ancient mythology, the trunk of a tree with a flag flying was given to Indra by Vishnu, the creation god of Hinduism, to help him gather strength and gain magic power to defeat all demons and ghosts. Indra likes a flower called Parijat in the Kathmandu Valley very much, but there is no flower in heaven. Once before the Tiki Festival, his mother needed this small flower with white petals and red stems. Indra immediately flew to the valley and became an ordinary man to pick it. The locals didn't know him, so they locked him up as a thief. His mother waited for a long time but failed, so she went down to the mortal world to search for her son. When Ordinary People learned the truth, they were shocked. They bowed down to the two gods and offered food and flowers as tribute. As a compensation and gift, Indra's mother promised to sprinkle fog and rain on the Kathmandu Valley in the dry autumn and winter, and promised to bring all the souls of those who died back to heaven. When Indra and his mother left the valley and flew to heaven, all the troops behind them suddenly fell into a lake in the west of the valley. At this time, the gods had disappeared, and all the souls had nowhere to go. Their relatives had to mourn and pray for them. Therefore, praying for relatives who died that year has also become a part of Indra Day [5].

Indra in ancient Indian mythology corresponds to the god of thunder in Indo Europe. He is homologous with Indra, the evil god in Iranian mythology. Indra is also known as "the slayer of Fulido" (v ṛ trah ā n) In the Avesta myth, the god of war, V ə R əθ Ra γ Name of na) [13]. "Indra" has existed long before the Aryan people of Mitanni. Indra was absorbed by Buddhism and called "Shitihuanyin" [1].
The name Indra first appeared in the tradition of the Aryan people (the common ancestor of the Indian and Iranian languages languages), which can be traced back to the treaty signed by Hitti and Mitanni in the ancient city of Boazkoi. In Rigveda, Indra is the king of the Devas, who once killed the serpent Frito with a vajra pestle, and thus created the world. However, in Persian mythology, Indra was demonized, and many of his prominent features appeared on other Ahura Mazda gods alone, especially Mitra, Wereslagna, and the legendary hero of Iran, Tana（ Θ Ra ē Taona). Titona became the person who killed the snake. Verrès Lagna had the transformation ability like Indra in Indian mythology, and Mitra's weapon was Vajra pestle. The reason why Indra was demonized is that some people think that after Zoroaster's reform, Indra's violent characteristics are too aggressive, which can only make him become a devil, but it is difficult to explain why these characteristics will be transplanted to other Ahura gods alone. The view that Iranians demonize their main gods because of cultural conflicts with Indian Aryan cannot provide evidence [16].
