Day 26 concludes Chapter 21, The Supernatural Powers of the Tathāgatas, includes Chapter 22, Transmission, and introduces Chapter 23, The Previous Life of Medicine-King Bodhisattva.

To sum up, all the teachings of the Tathāgata, all the unhindered, supernatural powers of the Tathāgata, all the treasury of the hidden core of the Tathāgata, and all the profound achievements of the Tathāgata are revealed and expounded explicitly in this sūtra. Therefore, keep, read, recite, expound and copy this sūtra, and act according to the teachings of it with all your hearts after my extinction!

And those who keep this sutra:

Anyone who keeps this sūtra
Will be able to see me.
He also will be able to see
Many-Treasures Buddha,
[The Buddhas of] my replicas,
And the Bodhisattvas whom I have taught today.

Anyone who keeps this sūtra will be able to cause me to rejoice.
He also will be able to bring joy
To [the Buddhas of] my replicas
And also to Many-Treasures Buddha who once passed away.

A light unto the world:

Anyone who understands why the Buddhas expound [many] sūtras,
Who knows the position [of this sūtra in the series of sūtras],
And who expounds it after my extinction
According to its true meaning,
Will be able to eliminate the darkness.
Of the living beings of the world where he walks about,
Just as the light of the sun and the moon
Eliminates all darkness.
He will be able to cause innumerable Bodhisattvas
To dwell finally in the One Vehicle.

Therefore, the man of wisdom
Who hears the benefits of these merits
And who keeps this sūtra after my extinction,
Will be able to attain
The enlightenment of the Buddha
Definitely and doubtlessly.

Why does the Buddha transmit the Dharma?

Keep, read, recite and expound [this sūtra in which the Dharma is given], and cause all living beings to hear it and know it! Why is that? It is because I have great compassion. I do not begrudge anything. I am fearless. I wish to give the wisdom of the Buddha, the wisdom of the Tathāgata, the wisdom of the Self-Existing One, to all living beings. Follow me, and study my teachings without begrudging efforts!

And in Chapter 23, The Previous Life of Medicine-King Bodhisattva, we learn of what it means to not begrudge efforts. Medicine-King Bodhisattva says:

‘I have now made offerings to the Buddha by my supernatural powers. But these offerings are less valuable than the offering of my own body.’

The light of his offering “illumined the worlds numbering eight thousands of millions of times the number of the sands of the River Ganges”
