Niganthasutta 2.1

2.1

“Tisso kho imā, abhaya, nijjarā visuddhiyo tena bhagavatā jānatā passatā arahatā sammāsambuddhena sammadakkhātā sattānaṃ visuddhiyā sokaparidevānaṃ samatikkamāya dukkhadomanassānaṃ atthaṅgamāya ñāyassa adhigamāya nibbānassa sacchikiriyāya.

“Abhaya, these three kinds of purification by wearing away have been rightly explained by the Blessed One, who knows and sees, the perfected one, the fully awakened Buddha. They are in order to purify sentient beings, to get past sorrow and crying, to make an end of pain and sadness, to discover the system, and to realize extinguishment.
