Day 17 covers all of Chapter 12, Devadatta, and opens Chapter 13, Encouragement for Keeping this Sutra.

Having last month considered Accumulated-Wisdom Bodhisattva’s question about Mañjuśrī’s efforts to teach the dharma, we consider Accumulated-Wisdom Bodhisattva’s objection that a dragon girl can become a Buddha quickly and meet the dragon girl.

Accumulated-Wisdom Bodhisattva said:

“As far as I know, [when he was a Bodhisattva,] Śākyamuni Buddha sought Bodhi, that is, enlightenment incessantly for innumerable kalpas. He accumulated merits by practicing austerities. Even the smallest part, even the part as large as a poppy-seed of this world-this world being composed of one thousand million Sumeru-worlds-is not outside the places where the Bodhisattva made efforts to save all living beings at the cost of his life. It was after doing all this that he attained Bodhi, that is, enlightenment. I do not believe that this girl will be able to attain perfect enlightenment[, that is, to become a Buddha] in a moment.”

No sooner had he said this than the daughter of the dragon king came to [Śākyamuni] Buddha. She worshipped [his feet] with her head, retired, stood to one side, and praised him with gāthās:

You know the sins and merits
Of all living beings.
You illumine the worlds of the ten quarters.
Your wonderful, pure and sacred body
Is adorned with the thirty-two major marks
And with the eighty minor marks.

Gods and men are looking up at you.
Dragons also respect you.
None of the living beings
Sees you without adoration.

Only you know that I [am qualified to] attain Bodhi
Because I heard [the Dharma].
I will expound the teachings of the Great Vehicle
And save all living beings from suffering.
