A Speaker on the Dhamma

At Savatthī. Then a certain bhikkhu approached the Blessed One, paid homage to him, sat down to one side, and said to him: “Venerable sir, it is said, ‘a speaker on the Dhamma, a speaker on the Dhamma.’ In what way, venerable sir, is one a speaker on the Dhamma?”

“Bhikkhu, if one teaches the Dhamma for the purpose of revulsion towards aging-and-death, for its fading away and cessation, one is fit to be called a bhikkhu who is a speaker on the Dhamma.

If one is practising for the purpose of revulsion towards aging-and-death, for its fading away and cessation, one is fit to be called a bhikkhu who is practising in accordance with the Dhamma.

If, through revulsion towards aging-and-death, through its fading away and cessation, one is liberated by nonclinging, one is fit to be called a bhikkhu who has attained Nibbāna in this very life.

“Bhikkhu, if one teaches the Dhamma for the purpose of revulsion towards birth … for the purpose of revulsion towards ignorance, for its fading away and cessation, one is fit to be called a bhikkhu who is a speaker on the Dhamma. If one is practising for the purpose of revulsion towards ignorance, for its fading away and cessation, one is fit to be called a bhikkhu who is practising in accordance with the Dhamma. If, through revulsion towards ignorance, through its fading away and cessation, one is liberated by nonclinging, one is fit to be called a bhikkhu who has attained Nibbāna in this very life.”
