“Bhikkhus, I will teach you the way that is suitable for uprooting all conceivings. Listen to that….
“And what, bhikkhus, is the way that is suitable for uprooting all conceivings? What do you think, bhikkhus, is the eye permanent or impermanent?”—“Impermanent, venerable sir.”—“Is what is impermanent suffering or happiness?”—sn.iv.25 “Suffering, venerable sir.”—“Is what is impermanent, suffering, and subject to change fit to be regarded thus: ‘This is mine, this I am, this is my self’?”—“No, venerable sir.”
“Are forms permanent or impermanent?… Is eye-consciousness … Is eye-contact … Is any feeling that arises with eye-contact as condition—whether pleasant or painful or neither-painful-nor-pleasant—permanent or impermanent?…
“Is the ear permanent or impermanent?… Is the mind … Is any feeling that arises with mind-contact as condition permanent or impermanent?”—“Impermanent, venerable sir.”—“Is what is impermanent suffering or happiness?”—“Suffering, venerable sir.”—“Is what is impermanent, suffering, and subject to change fit to be regarded thus: ‘This is mine, this I am, this is my self’?”—“No, venerable sir.” sn.iv.26
“Seeing thus, bhikkhus, the instructed noble disciple experiences revulsion towards the eye, towards forms, towards eye-consciousness, towards eye-contact, towards whatever feeling arises with eye-contact as condition—whether pleasant or painful or neither-painful-nor-pleasant. He experiences revulsion towards the ear … towards the mind … towards whatever feeling arises with mind-contact as condition…. 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.’
“This, bhikkhus, is the way that is suitable for uprooting all conceivings.”
