Day 22 covers all of Chapter 17, The Variety of Merits.

The chapter opens with lists and lists of the merits generated when those in the audience learned of the longevity of the Buddha. And these merits will continue accrue in the future:

Ajita! Anyone who hears that my life is so long, and understands it by faith even at a moment’s thought, will be able to obtain innumerable merits.

And:

It cannot be that the good man who obtained merits [by understanding my longevity by failh even at a moment’s thought] falters in walking the Way to Anuttara-samyak-sambodhi.

For Bodhisattvas and those who have firm faith:

The Bodhisattvas who have practiced the Way
For the past innumerable kalpas,
Will believe my longevity
When they hear of it.

They will receive this sutra on their heads,
And wish:
“May we live long and save all living beings
Just as the World-Honored One of today,
Who is the King of the Sakyas, [saves them]
By expounding the Dharma without fear
At the place of enlightenment
With [a voice like] a lion’s roar!
When we sit at the place of enlightenment,
Respected by all living beings,
May we preach that we also shall live
As long [as the World-Honored One of today]!”

Those who have firm faith,
And who are pure and upright,
And who hear much and memorize all teachings,
And who understand my words
According to their meaning,
Will have no doubts [about my longevity].

Limitless merits for anyone:

Anyone who not only understands
This sutra by faith
But also keeps, reads and recites it,
And copies it, or causes others to copy it,
And strews flowers, incense,
And incense powder to a copy of it,
And lights lamps of the perfumed oil
Of sumanas, campaka, and atimuktaka
Around the copy of this sutra
And offers the light thus produced to it,
Will be able to obtain innumerable merits.
His merits will be as limitless as the sky.

And a special position in the eyes of the Buddha for any teacher of the Dharma:

He is my son.
I will accept his place as mine.
I will be there.
l will walk, sit or recline there.
