Day 28 covers all of Chapter 24, Wonderful-Voice Bohisattva, and concludes the Seventh Volume of the Sūtra of the Lotus Flower of the Wonderful Dharma.
When Wonderful-Voice Bohisattva suggests to Pure-Flower-Star-King-Wisdom Buddha that he wants to visit Śākyamuni Buddha in the Sahā-World the Buddha tells him not judge by what he sees:
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, mountains1 and impurities. The Buddha [of that world] is short in stature. 2 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]!
Śākyamuni Buddha explains Wonderful-Voice Bohisattva’s greatest power:
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.
And the Gods on high benefit as well:
When [Śākyamuni Buddha] expounded this chapter of the Coming and Going of Wonderful-Voice Bodhisattva, forty-two thousand gods obtained the truth of birthlessness, and Flower-Virtue Bodhisattva obtained the ability to practice the samādhi for the Lotus Flower of the Wonderful Dharma.
