Deva was born around 200 years ago and passed away in 225 years ago. Some say she was born in 170 years ago and passed away in 270 years ago. It is translated as "heaven" (which is the heaven of heaven and man, not the heaven of the sky), also known as "Aryadeva". It is said that he once chose to offer one eye to God (some say to give one woman), so he is also known as "One eyed Deva" [1-2]. Deva was a disciple of Longshu, the founder of the Middle School of Indian Buddhism and the 15th ancestor of Zen Buddhism in the Western Regions. According to Tibetan Buddhist materials and the Records of the Western Regions of the Tang Dynasty, she was born in the Kingdom of Shizi (present-day Sri Lanka) and belonged to the Chadi tribe. After becoming a monk, he studied the Tripitaka extensively. Learn from India in the later stage and immerse yourself in the Dragon Tree Sect. The Biography of Deva Bodhisattva states that he was born in South India and belongs to the Brahmin caste.
Dippo lived in the third century AD and was known for his wisdom in debating. He often argued with outsiders and was later killed by them. Works such as "Four Hundred Discourses", "Hundred Discourses", and "Hundred Character Discourses" have been passed down and are important works of the Middle School.

The deeds of Deva are mainly recorded in the biographies written by Kumarash for him, as well as in Xuanzang's Records of the Western Regions. When Long Shu was preaching Buddhism in the Kingdom of South Josaro, he heard about it and went to debate with it. After several debates, he was convinced by the theory of the Long Shu and therefore converted to Buddhism under the throne of the Long Shu. Afterwards, he actively assisted Longshu in promoting the Mahayana Medieval philosophy, and also represented Longshu in many battles with the outside world. He once went to the city of Bozhali in Magadha on behalf of the Dragon Tree, defeated the heretics supported by the king, and established the authority of Buddhism here. Once, he engaged in a debate with the Brahmins at the confluence of the Jumuna River and the Ganges River in the kingdom of Borayaga (Allahabad). During this debate, he presented the viewpoint that "heaven" is "I", "I" is "you", and "you" is "dog", demonstrating the unattainable emptiness of pursuing pleasure and reality. This has had a significant impact in the history of Indian Buddhism. Based on this theory, he firmly opposes the idol worship of Brahmanism and advocates "moving people with majesty and subduing things with wisdom and virtue.". Due to his repeated victories over the Brahmin heretics, he was killed by a Brahmin disciple who felt ashamed and jealous. According to records, he, despite suffering from a heartbroken and dying state, still told his assassin which way to escape in order to avoid the revenge of his uninspired disciples, demonstrating an extraordinary spirit of humiliation, a broad mind of hatred and equality, and a true state of practice where both human and law are empty. According to Tibetan Buddhist records, he passed away in Langanada near the country of Kagami in southern India.

Deva and his master Long Shu have never been to China, but their "Zhonglun", "Bailun", and "Twelve Gates Lun" were translated into Chinese by the famous Kucha monk Kumarash who came to China during the Northern and Southern Dynasties, becoming the theoretical basis for promoting the establishment of the Mahayana Middle School's Three Treatises.

Deva developed the theory of dragon trees, believing that any method expressed in language is false; The laws of the concept of deviating from famous sayings are unknown. When refuting the Theravada and the external path, it advocates breaking without standing, thus elucidating the reality of all phenomena that are empty。

The image of Deva is not particularly distinctive, wearing a Panzhida hat, wearing an Indian style robe, and having her hands printed.
