Black sky (one of the Hindu gods)；Sanskrit (tianchengti: कष््; Iast: K ṛṣṇ a) is newly translated as "Krishna" and also translated as "Krishna". Sanskrit means black, because black can absorb seven colors in the spectrum, representing all his attraction. Black sky is an old translation of Buddhism. It is one of the most widely worshipped Hindu gods. It is regarded as the eighth embodiment of Vishnu. It is the head of the gods and the Lord of the world. Be careful not to confuse it with another Hindu God "big black sky", which is the embodiment of Shiva and "black sky" is the embodiment of Vishnu.

Heitian is the incarnation of Vishnu, the son of Vasudeva and devaji in Indian mythology. The image of Heitian has many meanings, integrating various myths and even historical archetypes. It is speculated that the "black" of Heitian is a proof of the origin of its image of the South Indian darapitan. The skin color of black sky is dark blue or dark purple (less if it is molded into all black, dark green or dark brown), just like the color of rain clouds to save deadly drought. According to its nature, Heitian is first of all a protector and deliverer, but for Indians, the word "black" in "Heitian" also has some ominous meaning; In Vedic times and later, various demons - Ashura also used this name. In Jain and Buddhist mythology, Heitian is a negative image (Buddhists think he is the head of the black devil and the enemy of the Buddha). In Hindu mythology, the evil characteristic of black sky is interpreted as the inconceivability of God, which is not bound by human norms, but usually takes a secondary position or whitewash. The earliest mention of the black sky is the Gozan Upanishads, which says that he is a disciple of Gura Yangqi rasa, but it is not clear whether it is the black sky described in Mahabharata, kholi lineage and various past books. In the epic Mahabharata, Heitian is mainly an ally of samurai, statesman and five sons of Pandu. But in relations with the enemy, faith is sometimes disregarded. In the Bhagavad Gita, Heitian is the emperor of azuna. Before the battle of Gulu, he appeared as the supreme god Vishnu and talked about religious philosophy with azuna. His speech is called the Bhagavad Gita. Among the ten incarnations of Vishnu, Heitian ranks eighth. The Bhagavad Puranas ranks 20th among the 22 incarnations of shiviru. Bhagavad Puranas, Vishnu Puranas, and later Brahma Puranas and other Puranas describe the "biography" of Heitian from a theological point of view. The sinful king of Ganza ruled the state of motura. Vishnu decided to be born as a man to save his land. The king of Ganza heard the prophecy that he would die at the hands of his cousin devaji's eighth son. So he killed all the sons of divagi and posudeva, and only dalirama, the seventh son, was spared. As soon as the eighth son Heitian was born, posutiva skillfully crossed him to the other bank of the river and handed him over to the shepherd. King Ganza learned that the newborn was missing and ordered to kill all babies in the country. In Heitian's childhood, his naughtiness (stealing the butter of his adoptive mother, stealing the clothes of the shepherds taking a bath, etc.) and meritorious deeds (killing the devil sent by the king of Ganza, sucking out the flame of the forest fire, saving the cattle and shepherds, defeating the king of snake, etc.) are the most popular themes of Indian poetry. The most popular story is the story of shepherd girls falling in love with young black sky. As soon as the shepherds heard the reed flute in the dark, they left their husbands and housework and ran to the river to dance with him. Indians interpret the shepherds' devotion to the dark sky as a symbol of the human soul's desire to integrate with God. But God is elusive and unreachable. Finally, Heitian left the shepherds to fulfill his duty - to kill the king of Ganza. He changed from a shepherd to a warrior and politician, killed the tyrant, restored the rule of justice, and protected the people from the demons who avenged Ganza. Heitian had eight wives at first, and then he married 16100 wives. He had a wonderful way to be with all his wives at the same time. He gave birth to many offspring. After the battle of the wild of Gulu, Heitian decided to return to heaven, destroy the city of yadu first, and then die under the arrow of a hunter who mistakenly regarded him as a wild deer. In medieval Indian literature, the image of amorous dark sky is very popular. His main lover is Rodo, the shepherd girl. In other parts of India, it is rumini. In poetry and painting, this image has been interpreted in various ways. Some are interpreted as religious fable images, while others are interpreted as secular images. Sometimes the boundary between the two is difficult to distinguish. In the 19th-20th century, some Indian writers influenced by European culture wanted to "wash away" the pornographic elements in Heitian and described him as a model of national political activists. Black sky myths and life legends are similar to Jesus Christ, and the pronunciation of his name is also similar. Therefore, some researchers assume that black sky may be a variant of Christ brought by nomads to India. But there is no strong evidence for this hypothesis。
