What is Tianbi? What is it?

Celestial burial is a traditional way of funeral for ethnic minorities such as Mongolia and Tibet. After death, people take their bodies to designated places for eagles (or other birds and animals) to swallow, thinking that they can take them to heaven. Like burial, water burial and cremation, it is a kind of belief, a way to express the dead, and its essence is a social and cultural phenomenon. Its origin, form, content and the implementation of the ceremony are all influenced by natural geographical environment, business methods, foreign culture and other factors. Therefore, different historical periods, different countries and regions, different nationalities and even different social classes will form different celestial burial ceremonies. There are records about celestial burial in China ancient books. For example, "Those who were buried in ancient times were paid for their thick clothes, but they were buried in the fields without sealing the trees"-"The Book of Changes" "There were also those who did not bury their relatives, and their relatives died and entrusted them to the valley. He wants to stop it, the fox wants to eat it, and the flies and mosquitoes want to suck it. " -"Mencius Teng Wengong". In some areas of modern society, celestial burial ceremonies still exist among people. For example, in Tibet, the celestial burial master turned his back to the sky, broke his limbs, tore off the skin in the center of his body and shoulders to expose his muscles, and then retreated, where vultures pecked everywhere. When the skeleton was left on the celestial burial platform, the celestial burial master smashed the skeleton into a ball with stones, and the vultures were in a mess again, and the food was gone, and people around them began to bow down. Another example is the Masai people living in East Africa. After their death, they washed the whole body of the deceased with water, carefully applied a layer of cream and placed it in the center of the room. Relatives knelt silently around the body for a day, and then the elders in the village led the way. Everyone carried the body to the wilderness and left it there for wild animals to swallow and birds to peck, thus indicating that the Masai people died in different lands. For another example, there are still celestial burial ceremonies among Parsis in India. Among the Parsis, "most members still believe in Zoroastrianism and maintain their original customs". The existing Zoroastrianism classic Zend-Areta records that Zoroastrianism "wants to put the dead on the top of the mountain where birds and animals haunt and let them eat their beaks".
