sn.22.61 Saṁyutta Nikāya (Linked Discourses)

At Savatthi. “Bhikkhus, form is burning, feeling is burning, perception is burning, volitional formations are burning, consciousness is burning. Seeing thus, bhikkhus, the instructed noble disciple experiences revulsion towards form, revulsion towards feeling, revulsion towards perception, revulsion towards volitional formations, revulsion towards consciousness. Experiencing revulsion, he becomes dispassionate. Through dispassion his mind is liberated. When it is liberated there comes the knowledge: ‘It’s liberated.’ He understands: ‘Destroyed is birth, the holy life has been lived, what had to be done has been done, there is no more for this state of being.’”
