[336] "When his mind (citta) is thus concentrated (samādhi) — purified, cleansed, unblemished, rid of defilements, malleable, wieldy, steady, and attained to imperturbability — he directs and inclines his mind to the knowledge (ñāṇa) of the destruction of the taints (āsava). He understands as it really is: 'This is suffering (dukkha)'; he understands as it really is: 'This is the origin of suffering'; he understands as it really is: 'This is the cessation of suffering'; he understands as it really is: 'This is the path of practice leading to the cessation of suffering'; he understands as it really is: 'These are the taints'; he understands as it really is: 'This is the origin of the taints'; he understands as it really is: 'This is the cessation of the taints'; he understands as it really is: 'This is the path of practice leading to the cessation of the taints.' When he thus knows and thus sees, his mind is liberated from the taint of sensuality, his mind is liberated from the taint of existence, his mind is liberated from the taint of ignorance (avijjā). When it is liberated, there comes the knowledge: '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 nothing further for this state of being.'
"Just as, young man, there might be a lake in a mountain glen — clear, limpid, unclouded — and a man with good eyes, standing on the bank, would see oyster shells and mussels, gravel and pebbles, and shoals of fish moving about or standing still; and it would occur to him: 'This lake is clear, limpid, unclouded; and here are these oyster shells and mussels, gravel and pebbles, and shoals of fish, moving about or standing still' — even so, young man, a bhikkhu … . In that, young man, a bhikkhu, when his mind is thus concentrated … attained to imperturbability, directs and inclines his mind to the knowledge of the destruction of the taints; he understands as it really is: 'This is suffering' … he understands as it really is: 'This is the path of practice leading to the cessation of the taints'; when he thus knows and thus sees, his mind is liberated from the taint 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: 'It is liberated'; he understands: 'Birth is destroyed, the holy life has been lived, what had to be done has been done, there is nothing further for this state of being' — this too pertains to his wisdom."
