Samyuktagama (Sanskrit fragments) 189.4

189.4

爾時，世尊告諸比丘：「於眼當正思惟、觀察無常。所以者何？於眼正思惟、觀察無常故，於眼欲貪斷，欲貪斷故，我說心正解脫。耳、鼻、舌、身、意，正思惟、觀察故，欲貪斷，欲貪斷者，我說心正解脫。如是，比丘！心正解脫者，能自記說：『我生已盡，梵行已立，所作已作，自知不受後有。』」

It was then that the Bhagavān addressed the monks, “One should correctly contemplate the eye and observe that it’s impermanent. Why is that? By correctly contemplating the eye and observing that it’s impermanent, desire and greed for the eye are ended. I say the mind is correctly liberated because desire and greed are ended.

“By correctly contemplating the ear … nose … tongue … body … mind, desire and greed [for the mind] are ended. When desire and greed are ended, I say the mind is correctly liberated.

“Thus, monks, someone who’s mind is correctly liberated can declare about themselves: ‘My births have been ended, the religious practice has been established, and the task has been accomplished. I myself know that I won’t be subject to a later existence.’”
