The Second Discourse on Perception
62.
"Monks, these five perceptions, when developed and cultivated, are of great fruit and great benefit, grounded upon the Deathless, having the Deathless as their final goal.
What five?
Perception of impermanence, perception of non-self, perception of death, perception of repulsiveness in food, perception of discontent with the whole world -
these, monks, are the five perceptions which, when developed and cultivated, are of great fruit and great benefit, grounded upon the Deathless, having the Deathless as their final goal."
