SN35.165 — Micchādiṭṭhipahāna Sutta
Thus have I heard. On one occasion, a certain disciple approached the Blessed One, and after approaching, he sat down to one side. Sitting there, the disciple said to the Blessed One, Venerable sir, how does one know and see so that wrong view is abandoned?
The Blessed One replied, Disciple, when one knows and sees the eye as impermanent, wrong view is abandoned. When one knows and sees forms as impermanent, wrong view is abandoned. When one knows and sees eye-consciousness as impermanent, wrong view is abandoned. When one knows and sees eye-contact as impermanent, wrong view is abandoned. Whatever feeling arises with mind-contact as condition: be it pleasant, painful, or neither-painful-nor-pleasant: that too, when known and seen as impermanent, leads to the abandonment of wrong view. Thus, disciple, by knowing and seeing in this way, wrong view is abandoned.
