The Discourse on Reviewing
53.
Thus have I heard.
On one occasion the Blessed One was dwelling at Sāvatthī in Jeta's Grove, Anāthapiṇḍika's park.
Now at that time the Blessed One was seated reviewing his own many evil unwholesome mental states as abandoned, and many wholesome mental states as having gone to fulfilment through development.
Then the Blessed One, having understood his own many evil unwholesome mental states as abandoned and many wholesome mental states as having gone to fulfilment through development, at that time uttered this inspired utterance -
"It was before, then it was not; it was not before, then it was;
It neither was nor will be, nor is it found at present." The third.
