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.

Day 21 covers all of Chapter 16, The Duration of the Life of the Tathāgata.

Having last month considered the Eternal Buddha’s purpose, we come to the duration of the life of the Tathāgata.

“Good men! The duration of my life, which I obtained by the practice of the way of Bodhisattvas, has not yet expired. It is twice as long as the length of time as previously stated. Although I shall never enter into Nirvāṇa, I say to men of little virtue, ‘I shall pass away.’ I teach them with this expedient. Why is that? It is because, if they see me for a long time, they will not plant the roots of good, but become poor and base, and cling to the five desires so much that they will be caught in the nets of wrong views. If they think that I am always here, and do not think that I will pass away, they will become too arrogant and lazy to realize the difficulty of seeing me, and they will not respect me. Therefore I say [to them] expediently, ‘Bhikṣus, know this! It is difficult to see a Buddha who appears in [this] world.’ Why is that? It is because some men of little virtue cannot see me even during many hundreds of thousands of billions of kalpas while the others can. Therefore, I say [to them], ‘Bhikṣus! It is difficult to see a Tathāgata.’ Those who hear this and know that it is difficult to see me, will adore me, admire me, and plant the roots of good. Therefore l say [to them], ‘I shall pass away,’ although I shall not.

“Good men! All the Buddhas, all the Tathāgatas, do the same as I do. [They expound their teachings] for the purpose of saving all living beings. Therefore, [their teachings] are true, not false.

The Daily Dharma from March 30, 2017, offers this:

Day 20 completes Chapter 15, The Appearance of Bodhisattvas from Underground, and concludes the Fifth Volume of the Sutra of the Lotus Flower of the Wonderful Dharma.

Having last month finished Chapter 15, it time to start over with the Buddha’s response to the greetings of the four great Bodhisattvas.

Thereupon the World-Honored One said to them in the presence of the great multitude of Bodhisattvas:

“Truly, truly good men! I am peaceful. l am in good health. The living beings are ready to be saved. They do not fatigue me because I already taught them in their consecutive previous existences, and also because they have already honored the past Buddhas respectfully and planted the roots of good. As soon as they saw me and heard my teachings, they received my teachings by faith and entered into the wisdom of the Tathāgata, except those who had previously studied and practiced the teachings of the Lesser Vehicle. Now I am causing [the followers of the Lesser Vehicle] to hear this sūtra and to enter into the wisdom of the Buddha.”

Thereupon the [four] great Bodhisattvas sang in gāthās:

Excellent, excellent, Great Hero!
World-Honored One!
The living beings are ready to be saved
Because in their previous existence
They already asked the [past] Buddhas
About their profound wisdom,
And having heard about it, understood it by faith.
We rejoice at seeing you.

Thereupon the World-Honored One praised the leading great Bodhisattvas, saying, “Excellent, excellent, good men! [l am glad that] you rejoice at seeing me.”

The Daily Dharma from Oct. 18, 2016, offers this:

Truly, truly good men! I am peaceful. I am in good health. The living beings are ready to be saved. They do not fatigue me because I already taught them in their consecutive previous existences, and also because they have already honored the past Buddhas respectfully and planted the roots of good.

The Buddha makes this proclamation to the leaders of the Bodhisattvas from Underground in Chapter Fifteen of the Lotus Sūtra. These Bodhisattvas appeared when the Buddha asked who would teach the Lotus Sūtra after the Buddha’s death, and asked about the Buddha’s health and whether those he was teaching could keep what he provided for them. The Buddha assures us not only of the certainty of our future enlightenment, but that for us to receive his teaching, there was an earlier time, which we may have forgotten, when we met him. This awareness of our future and our past helps us to see our place in the world and maintain our determination to benefit all beings.

Day 19 concludes Chapter 14, Peaceful Practices, and begins Chapter 15, The Appearance of Bodhisattvas from Underground.

Having last month witnessed the arrival of Bodhisattvas from Underground, we greet them today.

Those Bodhisattvas who appeared from underground, came to Many-Treasures Tathāgata and Śākyamuni Buddha both of whom were in the wonderful stūpa of the seven treasures hanging in the sky. They [joined their hands together] towards the two World-Honored Ones, and worshiped their feet with their heads. Then they [descended onto the ground and] came to the Buddhas sitting on the lion-like seats under the jeweled trees, bowed to them, walked around them from left to right three times, joined their hands together respectfully, and praised them by the various ways by which Bodhisattvas should praise Buddhas. Then they [returned to the sky,] stood to one side, and looked up at the two World-Honored ones with joy. A period of fifty small kalpas elapsed from the Bodhisattva-mahāsattvas’ springing up from underground till the finishing of the praising of the Buddhas by the various ways by which Bodhisattvas should praise Buddhas. All this while Śākyamuni Buddha sat in silence. The four kinds of devotees also kept silence for the fifty small kalpas. By his supernatural powers, however, the Buddha caused the great multitude to think that they kept silence for only half a day. Also by the supernatural powers of the Buddha, the four kinds of devotees were able to see that the skies of many hundreds of thousands of billions of worlds were filled with those Bodhisattvas.
