Day 23 covers all of Chapter 18, The Merits of a Person Who Rejoices at Hearing This Sutra, and opens Chapter 19, The Merits of the Teacher of the Dharma.

Chapter 18 answers Maitreya’s question about the merits to be gained by those who “rejoice at hearing this Sūtra of the Lotus Flower of the Wonderful Dharma” after the Buddha’s extinction.

Thereupon the Buddha said to Maitreya Bodhisattva-mahāsattva: “Ajita! Suppose a bhikṣu, a bhikṣuṇī, an upāsaka, an upāsikā, or some other wise person, whether young or old, rejoices at hearing this sūtra in a congregation after my extinction. After leaving the congregation, he or she goes to some other place, for instance, to a monastery, a retired place, a city, a street, a town, or a village. There he or she expounds this sūtra, as he or she has heard it, to his or her father, mother, relative, friend or acquaintance as far as he or she can. Another person who has heard [this sūtra from him or her], rejoices, goes [to some other place] and expounds it to a third person. The third person also rejoices at hearing it and expounds it to a fourth person. In this way this sūtra is heard by a fiftieth person. Ajita! Now I will tell you the merits of the fiftieth good man or woman who rejoices at hearing [this sūtra]. Listen attentively!

Just how great are those merits?

Ajita! The merits of the fiftieth person who rejoices at hearing this Sūtra of the Lotus Flower of the Wonderful Dharma are immeasurable, limitless, asaṃkhya. Needless to say, so are the merits of the first person who rejoices at hearing [this sūtra] in the congregation. His merits are immeasurable, limitless, asaṃkhya and incomparable.

And sharing the sūtra brings specific rewards:

Anyone who, while sitting in the place of the expounding of the Dharma, persuades another person to sit down or shares his seat with him to hear [the Dharma] when he sees him coming to the place, in his next life by his merits, will be able to obtain the seat of King Śakra, of the Brahman Heavenly-King or of a wheel-turning-holy-king.

“Ajita! Anyone who[, while he is staying outside the place of the expounding of the Dharma,] says to another person, ‘Let us go and hear the sūtra called the Lotus Flower of the Wonderful Dharma which is being expounded [in that place],’ and causes him to hear it even for a moment, in his next life by his merits, will be able to live with the Bodhisattvas who obtain dhāraṇīs.

And in gāthās:

Anyone who persuades others to sit and hear this sūtra
In the place where the Dharma is expounded,
Will be able to obtain the seat of Śakra or of Brahman
Or of a wheel-turning-holy-king by his merits.

Needless to say, boundless will be the merits
Of the person who hears this sūtra with all his heart,
And expounds its meanings,
And acts according to its teachings.

The Merits of the Teacher of the Dharma (Chapter 19) are more profound:

“The good men or women who keep, read, recite, expound or copy this Sūtra of the Lotus Flower of the Wonderful Dharma, will be able to obtain:

• eight hundred merits of the eye,
• twelve hundred merits of the ear,
• eight hundred merits of the nose,
• twelve hundred merits of the tongue,
• eight hundred merits of the body,
• twelve hundred merits of the mind.

They will be able to adorn and purify their six sense-organs with these merits.”

The eyes and ears and other sense organs “given by their parents will be purified, not defied.” The merits will be obtained with his “natural” eyes and ears and other sense organs “Although he has not yet obtained heavenly” eyes and ears and other sense organs.
