[97] He dwells pervading one direction with a mind (citta) imbued with loving-kindness (mettā), likewise the second, likewise the third, likewise the fourth; thus above, below, across, everywhere, to all as to himself, he dwells pervading the entire world with a mind imbued with loving-kindness — abundant, exalted, immeasurable, without enmity, without ill will. With a mind imbued with compassion (karuṇā) … With a mind imbued with altruistic joy (muditā) … He dwells pervading one direction with a mind imbued with equanimity (upekkhā), likewise the second, likewise the third, likewise the fourth; thus above, below, across, everywhere, to all as to himself, he dwells pervading the entire world with a mind imbued with equanimity — abundant, exalted, immeasurable, without enmity, without ill will.
He understands: 'There is this; there is the inferior; there is the superior; there is an escape beyond this whole field of perception.' When he knows thus and sees thus, his mind is liberated from the taint (āsava) of sensuality, his mind is liberated from the taint of existence, his mind is liberated from the taint of ignorance. When it is liberated, there comes the knowledge (ñāṇa): 'It is liberated.' He understands: 'Birth (jāti) is destroyed, the holy life has been lived, what had to be done has been done, there is no more of this state of being.' This, bhikkhus, is called a bhikkhu bathed with the inner bathing.
