Sukhasutta

“Tisso imā, bhikkhave, vedanā. Katamā tisso? Sukhā vedanā, dukkhā vedanā, adukkhamasukhā vedanā— imā kho, bhikkhave, tisso vedanāti.

Pleasure

“Mendicants, there are these three feelings. What three? Pleasant, painful, and neutral feeling. These are the three feelings.

Sukhaṁ vā yadi vā dukkhaṁ, adukkhamasukhaṁ saha; Ajjhattañca bahiddhā ca, yaṁ kiñci atthi veditaṁ.

Whether it’s pleasant or painful, as well as what’s neutral, whatever there is that is felt internally and externally:

Etaṁ dukkhanti ñatvāna, mosadhammaṁ palokinaṁ; Phussa phussa vayaṁ passaṁ, evaṁ tattha virajjatī”ti.

having known, ‘this is suffering, deceptive, breaking apart’, seeing feelings vanish with every contact, that’s how they become free of desire for them.”
