2.2

Yāvañcidaṃ tena bhagavatā jānatā passatā arahatā sammāsambuddhena sambādhe okāsādhigamo anubuddho sattānaṃ visuddhiyā sokaparidevānaṃ samatikkamāya dukkhadomanassānaṃ atthaṅgamāya ñāyassa adhigamāya nibbānassa sacchikiriyāya.

How this Blessed One who knows and sees, the perfected one, the fully awakened Buddha, has found an opening amid confinement. It’s 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.
