66.8

'The Buddha addressed the monks: "The mother's milk you have drunk while transmigrating through birth and death is more than the waters of the Ganges River and the four great oceans. Why is this? In your long night, you were born among elephants and drank an immeasurable amount of mother's milk; or you were born as camels, horses, oxen, donkeys, and various birds and beasts, and drank an immeasurable amount of their mother's milk. When you were cast away in burial grounds during your long night, the pus and blood that flowed out were also like this; or when you fell into the hells, animals, and hungry ghosts, the marrow and blood that flowed out were also like this."'
