This paper is about Tibetan sky burial. It points out that sky burial arose not merely due to the geographical features of Tibet. Religious doctrines provided a unique meaning to make the differentiation from Zoroastrianism and other nationality's bird Buried. Though the practices of facing death are found in all periods of Indian Buddhism, yet there is no evidence of sky burial in India. The rite of Tibetan sky burial has two parts: the separation of the body and the mind of the deceased, and the dissection of the corpse to feed vultures. The first step delivers the mind to a better state. The second transforms the ordinary dead body into a holy meal for distinguish guests. Although the rite is connected to the 12th century practice of Chod, yet the first clear historical record of Tibetan sky burial is related to the founder of the Drikung Kahgyu School-Kyobpa Jigten Sumgön-who established the first place for sky burial. This tradition with its many sacred meanings has been handed down to the present. Tibetan sky burial is not only a funeral rite, but also a presentation of Buddhist culture which says that beyond the physical concern to emphasize the peace of mental consciousness, there is a transformation of the fear of death and attachment to one's own body, so as to attain ultimate spiritual happiness and liberation.
