[28] Then, while the Dhamma was being taught to the father of Yasa the clansman, as Yasa reviewed the plane (bhūmi) as it had been seen, as it had been known, his mind (citta) was liberated from the taints (āsava) through non-clinging. Then this occurred to the Blessed One: "While the Dhamma was being taught to the father of Yasa the clansman, as he reviewed the plane as it had been seen, as it had been known, his mind was liberated from the taints through non-clinging. Yasa the clansman is incapable of reverting to the lower life to enjoy sensual pleasures as he did formerly as a householder. What if I were now to relax that feat of psychic power (iddhābhisaṅkhāra)?" Then the Blessed One relaxed that feat of psychic power.
The merchant householder saw Yasa the clansman sitting there; having seen him, he said to Yasa the clansman: "Dear Yasa, your mother is lamenting, overcome with sorrow. Give your mother her life."
Then Yasa the clansman looked up at the Blessed One. Then the Blessed One said to the merchant householder: "What do you think, householder? The Dhamma was seen by Yasa the clansman with a trainee's (sekha) knowledge (ñāṇa), with a trainee's vision, just as it was by you. As he reviewed the plane as it had been seen, as it had been known, his mind was liberated from the taints through non-clinging. Would Yasa be capable, householder, of reverting to the lower life to enjoy sensual pleasures as he did formerly as a householder?"
"Certainly not, venerable sir."
"The Dhamma, householder, was seen by Yasa the clansman with a trainee's knowledge, with a trainee's vision, just as it was by you. As he reviewed the plane as it had been seen, as it had been known, his mind was liberated from the taints through non-clinging. Yasa the clansman, householder, is incapable of reverting to the lower life to enjoy sensual pleasures as he did formerly as a householder."
"It is a gain, venerable sir, for Yasa the clansman; it is well gained, venerable sir, by Yasa the clansman, inasmuch as the mind of Yasa the clansman has been liberated from the taints through non-clinging. May the Blessed One consent to accept my meal for today, venerable sir, with Yasa the clansman as his attendant ascetic (pacchāsamaṇa)." The Blessed One consented by silence. Then the merchant householder, having understood the Blessed One's consent, rose from his seat, paid homage to the Blessed One, circumambulated him keeping his right side toward him, and departed.
Then, not long after the merchant householder had departed, Yasa the clansman said this to the Blessed One: "Venerable sir, may I receive the going forth (pabbajjā) in the presence of the Blessed One; may I receive the full ordination (upasampadā)."
"Come, bhikkhu," the Blessed One said, "the Dhamma is well proclaimed; live the holy life (brahmacariya)."
That itself was the venerable one's full ordination.
Now at that time there were seven arahants in the world.
The Going Forth of Yasa is concluded.
