In the cave Cenote Angelita, Mexico.
30 meters deep, fresh water, then 60 meters deep – salty water and under me I see a river, island and fallen leaves…
Actually, the river, which you can see, is a layer of hydrogen sulphide.
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.”
The majority of Tibetans adhere to Buddhism, which teaches rebirth. There is no need to preserve the body, as it is now an empty vessel. Birds may eat it, or nature may let it decompose. So the function of the sky burial is simply the disposal of the remains. In much of Tibet the ground is too hard and rocky to dig a grave, and with fuel and timber scarce, a sky burial is often more practical than cremation.
