an.5.305 Aṅguttara Nikāya (Numbered Discourses)

“Bhikkhus, for direct knowledge of lust, five things are to be developed. What five? The perception of impermanence, the perception of suffering in what is impermanent, the perception of non-self in what is suffering, the perception of abandoning, and the perception of dispassion. For direct knowledge of lust, these five things are to be developed.”
