1"Bhikkhus, I say that the destruction of the taints is for one who knows and sees, not for one who does not know and does not see.[n.388] Cp. SN12.23 and SN22.101. For one who knows what, for one who sees what, does the destruction of the taints come about?

The destruction of the taints comes about for one who knows and sees: ‘This is suffering’;
for one who knows and sees: ‘This is the origin of suffering’;
for one who knows and sees: ‘This is the cessation of suffering’;
for one who knows and sees: ‘This is the way leading to the cessation of suffering.’

It is for one who knows thus, for one who sees thus, that the destruction of the taints comes about.

2"Therefore, bhikkhus, an exertion should be made to understand: ‘This is suffering.’[n.376] Tasmātiha bhikkhave idaṁ dukkhan ti yogo karaṇīyo. Spk: Since a concentrated bhikkhu understands the Four Noble Truths as they really are, therefore you should make an exertion to become concentrated in order to understand the four truths as they really are. And since the round of existence increases for those who do not penetrate them, but stops increasing from the time they are penetrated, therefore you should make an exertion to understand them, thinking, "Let the round not increase for us."
An exertion should be made to understand: ‘This is the origin of suffering.’
An exertion should be made to understand: ‘This is the cessation of suffering.’
An exertion should be made to understand: ‘This is the way leading to the cessation of suffering.’"

1"Jānatohaṁ, bhikkhave, passato āsavānaṁ khayaṁ vadāmi, no ajānato apassato. Kiñca, bhikkhave, jānato passato āsavānaṁ khayo hoti?

‘Idaṁ dukkhan’ti, bhikkhave, jānato passato āsavānaṁ khayo hoti, ‘Ayaṁ dukkhasamudayo’ti jānato passato āsavānaṁ khayo hoti, ‘Ayaṁ dukkhanirodho’ti jānato passato āsavānaṁ khayo hoti, ‘Ayaṁ dukkhanirodhagāminī paṭipadā’ti jānato passato āsavānaṁ khayo hoti.

Evaṁ kho, bhikkhave, jānato evaṁ passato āsavānaṁ khayo hoti.

2Tasmātiha, bhikkhave, ‘idaṁ dukkhan’ti yogo karaṇīyo … pe … ‘Ayaṁ dukkhanirodhagāminī paṭipadā’ti yogo karaṇīyo"ti.

Pañcamaṁ.
