The Discourse on the External Elimination of Delight
157.
"Monks, a monk sees material form, which is indeed impermanent, as impermanent; that is his right view.
Seeing rightly, he becomes disenchanted.
Through the elimination of delight, there is the elimination of lust;
through the elimination of lust, there is the elimination of delight.
Through the elimination of delight and lust, the mind is said to be well liberated.
Monks, a monk sees sounds, which are indeed impermanent...
odours...
flavours...
tangible objects...
mental phenomena as impermanent; that is his right view.
Seeing rightly, he becomes disenchanted.
Through the elimination of delight, there is the elimination of lust;
through the elimination of lust, there is the elimination of delight.
Through the elimination of delight and lust, the mind is said to be well liberated."
