Day 13 covers all of Chapter 8, The Assurance of Future Buddhahood of the Five Hundred Disciples.
Thereupon the Buddha, wishing to repeat what he had said, sang in gāthās:
Bhikṣus, listen to me attentively!
The Way practiced by my sons
Is beyond your comprehension
Because they learned how to employ expedients.Knowing that people wish to hear
The teachings of the Lesser Vehicle,
And that they are afraid of having the great wisdom,
[My sons, that is,] the Bodhisattvas transform themselves
Into Śrāvakas or cause-knowers,
And teach the people with innumerable expedients.Saying to the innumerable living beings, [for instance,]
“We are Śrāvakas.
We are far from the enlightenment of the Buddha,”
They save them, and cause them to attain [Śrāvakahood]
Even the lazy people who wish to hear the Lesser Vehicle
Will become Buddhas with this expedient in the course of time.My disciples are performing
The Bodhisattva practices secretly
Though they show themselves in the form of Śrāvakas.
They are purifying my world
Though they pretend to want little
And to shun birth-and-death.
In the presence of the people,
They pretend to have the three poisons and wrong views.
They save them with these expedients.
They change themselves into various forms.
If I speak of all their transformations,
The listeners will doubt me.Under hundreds of thousands of millions of past Buddhas,
This Pūrṇa practiced strenuously what he should do.
He expounded and protected
The teachings of those Buddhas.In order to obtain unsurpassed wisdom,
He became the most excellent disciple
Of those Buddhas.
He was learned and wise.
He expounded the Dharma without fear,
And made his listeners rejoice.
He was never tired
Of helping those Buddhas do their work.He obtained great supernatural powers
And the four kinds of unhindered eloquence.
Seeing who was clever, and who was dull,
He always expounded the Pure Dharma.He expounded the dharma of the Great Vehicle
To hundreds of thousands of millions of living beings,
And caused them to dwell in the Dharma
So that the worlds of those Buddhas might be purified.In the future also he will make offerings
To innumerable Buddhas, protect their right teachings,
Help them propagate their teachings,
And purify their worlds.He will always fearlessly expound the Dharma
With expedients.
He will save countless living beings
And cause them to have the knowledge of all things.He will make offerings to many Tathāgatas
And protect the treasure-store of the Dharma.
After that he will be able to become a Buddha
Called Dharma-Brightness.His world will be called Good-Purity.
It will be made of the seven treasures.
His kalpa will be called Treasure-Brightness.
There will be Bodhisattvas [in his world],
Many hundreds of millions in number.
They will have great supernatural powers.
They will be powerful and virtuous.
They will be seen throughout that world.Innumerable Śrāvakas will organize the Saṃgha.
They will have the three major supernatural powers,
The eight emancipations,
And the four kinds of unhindered eloquence.The living beings of that world will have no sexual desire.
They will be born without any medium.
They will be adorned with the marks [of the Buddha].
They will not think
Of any other food [than the two kinds of food]:
The delight in the Dharma, and the delight in dhyāna.
There will be neither women nor evil regions
In that world.Pūrṇa Bhikṣu will be able to obtain
All these merits,
And have his pure world
Inhabited by many sages and saints.
I have innumerable things to say of him.
I have told you only a few of them.
