16. Perception

“Monks, these nine perceptions, when developed & pursued, are of great fruit, of great benefit. They gain a footing in the deathless and have the deathless as their final end. Which nine?

“The perception of unattractiveness (of the body), the perception of death, the perception of the foulness in food, the perception of no-delight in any world, the perception of inconstancy, the perception of stress in inconstancy, the perception of not-self in stress, the perception of abandoning, the perception of dispassion.

“These nine perceptions, when developed & pursued, are of great fruit, of great benefit. They gain a footing in the deathless and have the deathless as their final end.”
