Bhavanasutta 5.2

5.2

Evamevaṃ kho, bhikkhave, bhāvanaṃ anuyuttassa bhikkhuno viharato kiñcāpi na evaṃ ñāṇaṃ hoti: ‘ettakaṃ me ajja āsavānaṃ khīṇaṃ, ettakaṃ hiyyo, ettakaṃ pare’ti, atha khvassa khīṇe ‘khīṇan’teva ñāṇaṃ hoti.

In the same way, when a mendicant is committed to development, they don’t know how much of the defilements were worn away today, how much yesterday, and how much previously. They just know what has been worn away.
