“Bhikkhus, for direct knowledge of lust, ten things are to be developed. What ten? The perception of impermanence, the perception of non-self, the perception of the repulsiveness of food, the perception of non-delight in the entire world, the perception of a skeleton, the perception of a worm-infested corpse, the perception of a livid corpse, the perception of a festering corpse, the perception of a fissured corpse, and the perception of a bloated corpse. For direct knowledge of lust, these ten things are to be developed.”
