“Sky burial or ritual dissection was once a common funerary practice in Tibet wherein a human corpse is cut in specific locations and placed on a mountaintop, exposing it to the elements or the mahabhuta and animals – especially to birds of prey. The location of the sky burial preparation and place of execution are understood in the Vajrayana traditions as charnel grounds. In Tibet the practice is known as jhator, which literally means, «giving alms to the birds»”. – Wikipedia
