“Bhikkhus, these ten perceptions, when developed and cultivated, are of great fruit and benefit, culminating in the deathless, having the deathless as their consummation. What ten? (1) The perception of unattractiveness, (2) the perception of death, (3) the perception of the repulsiveness of food, (4) the perception of non-delight in the entire world, (5) the perception of impermanence, (6) the perception of suffering in the impermanent, (7) the perception of non-self in what is suffering, (8) the perception of abandoning, (9) the perception of dispassion, and (10) the perception of cessation. These ten perceptions, when developed and cultivated, are of great fruit and benefit, culminating in the deathless, having the deathless as their consummation.” an.v.106
