Day 30 covers all of Chapter 26, Dhāraṇīs

The merits a single gāthā of four lines from the Lotus Sutra:

Thereupon Medicine-King Bodhisattva rose from his seat, bared his right shoulder, joined his hands together towards the Buddha, and said to him:

“World-Honored One! How many merits will be given to the good men or women who keep, read, recite, understand or copy the Sūtra of the Lotus Flower of the Wonderful Dharma?”

The Buddha said to him:

“Suppose some good men or women make offerings to eight hundred billion nayuta Buddhas, that is, as many Buddhas as there are sands in the River Ganges. What do you think of this? Are the merits given to them many or not?”

“Very many, World-Honored One!”

The Buddha said: “More merits will be given to the good men or women who keep, read or recite even a single gāthā of four lines of this sūtra, understand the meanings of it or act according to it.”

The vows of the 10 rākṣasīs daughters and their mother, the Mother-Of-Devils, and her children and attendants:

Anyone who does not keep our spells
But troubles the expounder of the Dharma
Shall have his head split into seven pieces
Just as the branches of the arjaka-tree [are split].

Anyone who attacks this teacher of the Dharma
Will receive the same retribution
As to be received by the person who kills his parents,
Or who makes [sesame] oil without taking out worms [from the sesame],
Or who deceives others by using wrong measures and scales,
Or by Devadatta who split the Saṃgha.

And in exchange, the Buddha promises them merits:

The Buddha said to the rākṣasīs:

“Excellent, excellent! Your merits will be immeasurable even when you protect the person who keeps only the name of the Sūtra of the Lotus Flower of the Wonderful Dharma. Needless to say, so will be your merits when you protect the person who keeps the sūtra itself, and makes to a copy of this sūtra hundreds of thousands of offerings such as flowers, incense, necklaces, powdered incense, incense applicable to the skin, incense to burn, streamers, canopies, music, and various lamps like lamps of butter oil, oil lamps, lamps of perfumed oil, lamps of sumanas-flower oil, lamps of campaka flower oil, lamps of vārṣika-flower oil, and lamps of utpala-flower oil. Kuntī! You [rākṣasīs] and your attendants should protect this teacher of the Dharma.”

Day 29 covers all of Chapter 25, The Universal Gate of World-Voice-Perceiver Bodhisattva.

A Bodhisattva with promise:

The Buddha said to Endless-Intent Bodhisattva: “Good man! If many hundreds of thousands of billions of living beings hear [the name of] World-Voice-Perceiver Bodhisattva and call his name with all their hearts when they are under various sufferings, World-Voice-Perceiver Bodhisattva will immediately perceive their voices, and cause them to emancipate themselves [from the sufferings].”

Among the long list of sufferings from which one can be emancipated:

Those who have much lust will be saved from lust if they constantly think of World-Voice-Perceiver Bodhisattva and respect him. Those who have much anger will be saved from anger if they constantly think of World-Voice-Perceiver Bodhisattva and respect him. Those who have much stupidity will be saved from stupidity if they constantly think of World-Voice-Perceiver Bodhisattva and respect him. Endless-Intent! World-Voice-Perceiver Bodhisattva has these great supernatural powers. He gives many benefits to all living beings. Therefore, they should constantly think of him.

Fruits of merits:

Endless-Intent! Because World-Voice-Perceiver Bodhisattva has these powers, the merits of those who respect him and bow to him will not be fruitless. Therefore, all living beings should keep the name of World-Voice-Perceiver Bodhisattva.

World-Voice-Perceiver Bodhisattva is not just a wishing stone. In the same manner as Wonderful-Voice Bohisattva, which was mentioned in Day 28, World-Voice-Perceiver Bodhisattva transforms into gods and others in order to expound the Dharma:

Endless-Intent Bodhisattva said to the Buddha: “World-Honored One! How does World-Voice-Perceiver Bodhisattva go about this Sāha-World? How does he expound the Dharma to the living beings? What expedients does he employ?”

The Buddha said to Endless-Intent Bodhisattva: “Good man! In a certain world, World-Voice-Perceiver Bodhisattva takes the shape of a Buddha and expounds the Dharma to those who are to be saved by a Buddha. He takes the shape of a Pratyekabuddha and expounds the Dharma to those who are to be saved by a Pratyekabuddha. He takes the shape of a Śrāvaka and expounds the Dharma to those who are to be saved by a Śrāvaka. He takes the shape of King Brahman and expounds the Dharma to those who are to be saved by King Brahman. He takes the shape of King Śakra and expounds the Dharma to those who are to be saved by King Śakra. He takes the shape of Freedom God and expounds the Dharma to those who are to be saved by Freedom God. He takes the shape of Great-Freedom God and expounds the Dharma to those who are to be saved by Great-Freedom God. He takes the shape of a great general in heaven and expounds the Dharma to those who are to be saved by a great general in heaven. He takes the shape of Vaiśravaṇa and expounds the Dharma to those who are to be saved by Vaiśravaṇa. He takes the shape of the king of a small country and expounds the Dharma to those who are to be saved by the king of a small country. He takes the shape of a rich man and expounds the Dharma to those who are to be saved by a rich man. …

“Endless-Intent! This World-Voice-Perceiver Bodhisattva does these meritorious deeds. He takes various shapes, walks about many worlds, and saves the living beings [of those worlds]. Make offerings to World-Voice-Perceiver Bodhisattva with all your hearts! This World-Voice-Perceiver Bodhisattva-mahāsattva gives fearlessness [to those who are] in fearful emergencies. Therefore, he is called the ‘Giver of Fearlessness’ in this Sahā-World.”

And in gāthās:

World-Voice-Perceiver will save
All living beings from misfortunes
And from innumerable sufferings of the world
By the wonderful power of his wisdom.

He has these supernatural powers.
He employs various expedients with his wisdom.
In the ten quarters there is no kṣetra
In which he does not appear at all.

Hell, the region of hungry spirits, and the region of animals,
That is, the [three] evil regions will be eliminated.
The sufferings of birth, old age, disease and death
Will gradually be eliminated.

He sees the truth of all things and their purity.
He sees all things with his great wisdom.
He sees all things with loving-kindness and compassion.
Think of him constantly! Look up at him constantly!

Day 28 covers all of Chapter 24, Wonderful-Voice Bohisattva.

Śākyamuni’s light illumines “one hundred and eight billion nayuta Buddha-worlds” in the east, including one in which a Buddha called Pure-Flower-Star-King-Wisdom is preaching. The light catches the attention of a Bodhisattva called Wonderful-Voice, and he asks Pure-Flower-Star-King-Wisdom for permission to visit the Sahā-World.

Obviously the Sahā-World is something of a low-rent area compared to the All-Pure-Light-Adornment world, and the Buddha feels compelled to warn Wonderful-Voice Bodhisattva:

Do not despise that world! Do not consider it to be inferior [to our world]! Good Man! The Sahā-World is not even. It is full of mud, stones, mountains and impurities. The Buddha [of that world] is short in stature. So are the Bodhisattvas [of that world]. You are forty-two thousand yojanas tall. I am six million and eight hundred thousand yojanas tall. You are the most handsome. You have thousands of millions of marks of merits, and your light is wonderful. Do not despise that world when you go there! Do not consider that the Buddha and Bodhisattvas of that world are inferior [to us]! Do not consider that that world is inferior [to ours]!

The message delivered by Wonderful-Voice Bodhisattva:

World-Honored One! I bring you a message from Pure-Flower-Star-King-Wisdom Buddha. [He wishes to say this.] Are you in good health? Are you happy and peaceful or not? Are the four elements of your body working in harmony or not? Are the worldly affairs bearable or not? Are the living beings easy to save or not? Do they not have much greed, anger, ignorance, jealousy, stinginess and arrogance, or do they? Are they not undutiful to their parents, or are they? Are they not disrespectful to śramaṇas, or are they? Do they not have wrong views, or do they? Are they not evil, or are they? Do they not fail to control their five desires, or do they? World-Honored One! Did they defeat the Māras, who are their enemies, or not? Is Many-Treasures Tathāgata, who passed away a long time ago and has now come here riding in the stūpa of the seven treasures, hearing the Dharma or not? [Pure-Flower-Star-King-Wisdom Buddha] also wishes to know whether Many-Treasures Tathāgata is peaceful and healthy, and able to stay long or not.

One of Wonderful-Voice Bodhisattva’s powers is the ability to transform himself. Śākyamuni Buddha explains to Flower-Virtue Bodhisattva:

Flower-Virtue! Now you see Wonderful-Voice Bodhisattva here and nowhere else. But formerly he transformed himself into various living beings and expounded this sūtra to others in various places. He became King Brahman, King Śakra, Freedom God, Great-Freedom God, a great general in heaven, Vaiśravaṇa Heavenly-King, a wheel-turning-holy-king, the king of a small country, a rich man, a householder, a prime minister, a brāhmaṇa, a bhikṣu, a bhikṣuṇī, an upāsaka, an upāsikā, the wife of a rich man, that of a householder, that of a prime minister, that of a brāhmaṇa, a boy, a girl, a god, a dragon, a yakṣa, a gandharva, an asura, a garuḍa, a kiṃnara, a mahoraga, a human being or a nonhuman being. [After he transformed himself into one or another of these living beings,] he expounded this sūtra, and saved the hellish denizens, hungry spirits, animals, and all the other living beings in the places of difficulties. When he entered an imperial harem, he became a woman and expounded this sūtra.

Flower-Virtue! This Wonderful-Voice Bodhisattva protects all living beings in this Sahā-World. He transforms himself into one or another of these various living beings in this Sahā-World and expounds this sūtra to all living beings without reducing his supernatural powers, [his power of] transformation, and his wisdom. He illumines this Sahā-World with the many [rays of light] of his wisdom, and causes all living beings to know what they should know.

As an aside, even the gods listen and learn:

When [Śākyamuni Buddha] expounded this chapter of the Coming and Going of Wonderful-Voice Bodhisattva, forty-two thousand gods obtained the truth of birthlessness.

Day 27 concludes Chapter 23, The Previous Life of Medicine-King Bodhisattva

The source of greatest merit:

[T]he merits to be given to the person who fills the one thousand million Sumeru-worlds with the seven treasures and offers that amount of the seven treasures to the Buddhas, to the Great Bodhisattvas, to the Pratyekabuddhas, and to the Arhats, are less than the merits to be given to the person who keeps even a single gāthā of four lines of this Sūtra of the Lotus Flower of the Wonderful Dharma.

The great wish granting sutra:

Star-King-Flower! This sūtra saves all living beings. This sūtra saves them from all sufferings, and gives them great benefits. All living beings will be able to fulfill their wishes by this sūtra just as a man who reaches a pond of fresh water when he is thirsty, just as a man who gets fire when he suffers from cold, just as a man who is given a garment when he is naked, just as a party of merchants who find a leader, just as a child who meets its mother, just as a man who gets a ship when he wants to cross [a river], just as a patient who finds a physician, just as a man who is given a light in the darkness, just as a poor man who gets a treasure, just as the people of a nation who see a new king enthroned, just as a trader who reaches the seacoast. Just as a torch dispels darkness, this Sūtra of the Lotus Flower of the Wonderful Dharma saves all living beings from all sufferings, from all diseases, and from all the bonds of birth and death.

Respecting the keeper of this sutra:

Star-King-Flower! Strew blue lotus flowers and a bowlful of powdered incense to the person who keeps this sūtra when you see him! After strewing these things [to him], you should think, ‘Before long he will collect grass [for his seat], sit at the place of enlightenment, and defeat the army of Māra. He will blow the conch-shell horn of the Dharma, beat the drum of the great Dharma, and save all living beings from the ocean of old age, disease and death.’

In this way, those who seek the enlightenment of the Buddha should respect the keeper of this sūtra whenever they see him.
