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

Having last month covered the gāthās and the benefits of hearing of the longevity of the Buddha, we conclude Maitreya’s gāthās of praise for the Buddha.

You expounded the teachings
Immeasurable and inconceivable,
And benefited living beings
As limitless as the sky.

[The gods] rained down mandārava-flower ,
And mahā-mandārava-flowers of heaven.
Sakras and Brahmans came from the [other] Buddha-worlds
As many as there are sands in the River Ganges.

[The gods] rained down candana and aloes [powder],
And offered it to the Buddhas.
The powder came down fluttering
Just as birds fly down from the sky.

Heavenly drums automatically sounded
Wonderful in the sky.
Thousands of billions of heavenly garments
Whirled down.

[The gods] burned priceless incense which was put
In wonderful incense-burners of many treasures.
The incense-burners automatically went around,
And the odor was offered to the World-Honored Ones.

The great Bodhisattvas lined up vertically one upon another
To the Heaven of Brahman, holding
Billions of lofty and wonderful canopies and streamers
Made of the seven treasures.

[The great Bodhisattvas] hoisted before the Buddha
Jeweled banner adorned with excellent streamers.
They also praised the Tathāgatas
With tens of millions of gāthās.

I have never seen these things before.
All living beings
Rejoice at hearing
That the duration of your life is immeasurable.

Your fame is extended over the worlds of the ten quarters.
You benefit all living beings.
The root of good which they have planted
Will help them aspire for unsurpassed [enlightenment].

Underscore “The root of good which they have planted
Will help them aspire for unsurpassed [enlightenment]” and visualize a root feeding a tree of enlightenment.
