Day 31 covers Chapter 27, King Wonderful-Adornment as the Previous Life of a Bodhisattva.
Having last month witnessed the two sons asking their mother and the mother allowing her sons to join the Buddha, we consider the preparations to see Cloud-Thunderpeal-Star-King-Flower-Wisdom Buddha.
“Thereupon the [father came to them. The] two sons said to their parents, ‘Excellent, Father and Mother! Go to Cloud-Thunderpeal-Star-King-Flower-Wisdom Buddha, see him, and make offerings to him because to see a Buddha is as difficult as to see an udumbara flower or as for a one-eyed tortoise to find a hole in a floating piece of wood! We accumulated so many merits in our previous existence that we are now able to meet the teachings of the Buddha in this life of ours. Allow us to renounce the world because it is difficult to see a Buddha, and also because it is difficult to have such a good opportunity as this to see him.’
“Thereupon the eighty-four thousand people in the harem of King Wonderful-Adornment became able to keep the Sūtra of the Lotus Flower of the Wonderful Dharma.
“Pure-Eyes Bodhisattva had already practiced the samādhi for the Lotus Flower of the Wonderful Dharma for a long time. Pure-Store Bodhisattva had already practiced the samādhi for the release from evil regions in order to release all living beings from evil regions for many hundreds of thousands of billions of kalpas.
“Now the queen practiced the samādhi for the assembly of Buddhas, and understood the treasury of their hidden core. The two sons led their father by these expedients and caused him to understand the teachings of the Buddha by faith and to wish [to act according to those teachings].
Nichiren explains the target audience for this chapter in his letter “Response to My Lady Nichinyo”:
The chapter “Wonderful Adornment King” is expounded for women. It tells of a wife recommending Buddhism to her husband. If a wife recommends the Lotus Sūtra to her husband in the Latter Age of Degeneration, her merit will be the same as that of Lady Jōtoku, or Pure Virtue. The merits would be much more upon you both, a husband and wife, who believe together in the Lotus Sūtra. You are like a bird that has two wings or a vehicle with two wheels. Everything will surely be achieved by you. With heaven and earth, sun and moon, sunshine and rain, plants and trees of the merits will bear blossoms and fruit.
