Perceptions (2nd)

“Mendicants, these ten perceptions, when developed and cultivated, are very fruitful and beneficial. They culminate in the deathless and end with the deathless.
What ten?
The perceptions of impermanence, not-self, death, repulsiveness of food, dissatisfaction with the whole world, a skeleton, a worm-infested corpse, a livid corpse, a split open corpse, and a bloated corpse.
These ten perceptions, when developed and cultivated, are very fruitful and beneficial. They culminate in the deathless and end with the deathless.”
