Day 28 covers all of Chapter 24, Wonderful-Voice Bodhisattva, and concludes the Seventh Volume of the Sutra of the Lotus Flower of the Wonderful Dharma.
Having last month heard Flower-Virtue Bodhisattva asks the Buddha about the name of the samadhi practiced by Wonderful-Voice Bodhisattva-mahāsattva, we conclude Chapter 24, Wonderful-Voice Bodhisattva.
Thereupon Wonderful-Voice Bodhisattva-mahāsattva made offerings to Śākyamuni Buddha and to the stupa of Many-Treasures Buddha, [benefited the living beings of the Sahā World,] and left for his home world[, accompanied by the eighty-four thousand Bodhisattvas]. As they passed through the [one hundred and eight billion nayuta] worlds, the ground of those worlds quaked in the six ways; lotus-flowers of treasures rained down; and hundreds of thousands of billions of kinds of music were made. Having reached his home world, accompanied by the eighty-four thousand Bodhisattvas who surrounded him, he came to Pure-Flower-Star-King-Wisdom Buddha. He said to the Buddha:
“World-Honored One! I went to the Sahā-World and benefited the living beings there. I saw Śākyamuni Buddha and the stupa of Many-Treasures Buddha. I bowed and made offerings to them. I also saw Mañjuśrī Bodhisattva, the Son of the King of the Dharma. [I also saw] Medicine-King Bodhisattva, Endeavor-Power-Obtainer Bodhisattva, Brave-In-Giving Bodhisattva, and others. I also caused these eighty-four thousand Bodhisattvas to obtain the ability to practice the samadhi by which they could transform themselves
into any other living being.”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 samadhi for the Lotus Flower of the Wonderful Dharma.
[Here ends] the Seventh Volume of the Sūtra of the Lotus Flower of the Wonderful Dharma.
Nichiren offers a detail about the past life of Wonderful-Voice Bodhisattva that ties him with Chapter 27, King Wonderful-Adornment as the Previous Life of a Bodhisattva:
It says in the “Bodhisattva Wonderful Voice” chapter that there was a bodhisattva named Myōon or Wonderful Voice, in the eastern world of the Buddha King Wisdom of the Pure Flower Constellation. This bodhisattva was once Lady Jōtoku, or Pure Virtue, the wife of King Wonderful Adornment in the age of the Buddha Cloud Thunder Roll King. She became Bodhisattva Wonderful Voice by virtue of venerating the Lotus Sūtra. When Śākyamuni Buddha expounded the Lotus Sūtra in the Sahā World, she came and promised that she would protect all women who upheld the Lotus Sūtra in the Latter Age of Degeneration.
