an.5.61 Aṅguttara Nikāya (Numbered Discourses)

“Bhikkhus, these five perceptions, when developed and cultivated, are of great fruit and benefit, culminating in the deathless, having the deathless as their consummation. What five? The perception of unattractiveness, the perception of death, the perception of danger, the perception of the repulsiveness of food, and the perception of non-delight in the entire world. These five perceptions, when developed and cultivated, are of great fruit and benefit, culminating in the deathless, having the deathless as their consummation.”
