Day 13 covers all of Chapter 8, The Assurance of Future Buddhahood of the Five Hundred Disciples.
Having last month considered the reaction of the five hundred Arhats and heard the Parable of the Priceless Gem, concluded Chapter 8, The Assurance of Future Buddhahood of the Five Hundred Disciples, we begin again with Pūrṇa’s reaction to the Buddha’s expedient teaching.
Thereupon Pūrṇa, the son of Maitrāyanī having heard from the Buddha the Dharma expounded with expedients by the wisdom [o£ the Buddha] according to the capacities of all living beings, and having heard that [the Buddha] had assured the great disciples of their future attainment of Anuttara-samyak-saṃbodhi, and also having heard of the previous life of the Buddha, and also having heard of the great, unhindered, supernatural powers of the Buddhas, had the greatest joy that he had ever had, became pure in heart, and felt like dancing [with joy]. He rose from his seat, came to the Buddha, and worshipped him at his feet with his head. Then he retired to one side of the place, looked up at the honorable face with unblenching eyes, and thought:
‘The World-Honored One is extraordinary. What he does is exceptional. He expounds the Dharma with expedients by his insight according to the various natures of all living beings of the world, and saves them from various attachments. The merits of the Buddha are beyond the expression of our words. Only the Buddha, only the World-Honored One, knows the wishes we have deep in our minds.’
