[441] Then a number of bhikkhus approached the Blessed One … Sitting to one side, those bhikkhus said this to the Blessed One: "What now, venerable sir, is feeling (vedanā)? What is the origin of feeling? What is the way of practice leading to the origin of feeling? … What is the gratification (assāda) in feeling? What is the danger (ādīnava)? What is the escape (nissaraṇa)?"
"Bhikkhus, there are these three feelings: pleasant feeling, painful feeling, and neither-painful-nor-pleasant feeling. These, bhikkhus, are called feelings. With the origin of contact (phassa) there is the origin of feeling. Craving (taṇhā) is the way of practice leading to the origin of feeling. With the cessation of contact … The removal of desire and lust (chandarāga) for feeling, the abandoning of desire and lust — this is the escape from feeling."
