Day 14 covers all of Chapter 9, The Assurance of Future Buddhahood of the Śrāvakas Who Have Something More to Learn and the Śrāvakas Who Have Nothing More to Learn, and opens Chapter 10, The Teacher of the Dharma.
Limited to just one topic, I’m going to skip Ananda and Rahula and the Sravakas, some of whom have something more to learn and some of whom have nothing more to learn, and focus on the promise contained at the start of Chapter 10, The Teacher of the Dharma.
Thereupon the World-Honored One said to Medicine-King Bodhisattva in the presence of the eighty thousand great men:
Medicine-King! Do you see the innumerable gods, dragon-kings, yaksas, gandharvas, asuras, garudas, kirnnaras, mahoragas, men, and nonhuman beings, and [the four kinds of devotees:] bhiksus, bhiksunis, upasakas, and upasikas, and those who are seeking Sravakahood or Pratyekabuddhahood or the enlightenment of the Buddha in this great multitude? If in my presence any of them rejoices, even on a moment’s thought, at hearing even a gatha or a phrase of the Sutra of the Lotus Flower of the Wonderful Dharma, I will assure him of his future Buddhahood, saying to him, ‘You will be able to attain Anuttara-samyak-sarnbodhi.’
The Buddha said to Medicine-King:
If after my extinction anyone rejoices, even on a moment’s thought, at hearing even a gatha or a phrase of the Sutra of the Lotus Flower of the Wonderful Dharma, I also will assure him of his future attainment of Anuttara-samyak-sambodhi. If anyone keeps, reads, recites, expounds and copies even a gatha of the Sutra of the Lotus Flower of the Wonderful Dharma, and respects a copy of this sutra just as he respects me, and offers flowers, incense, necklaces, incense powder, incense applicable to the skin, incense to burn, canopies, banners, streamers, garments and music to it, or just joins his hands together respectfully towards it, Medicine-King, know this, he should be considered to have appeared in the world of men out of his compassion towards all living beings, although he already made offerings to ten billion Buddhas and fulfilled his great vow under those Buddhas in a previous existence.
And in gathas:
Anyone who keeps
The Sutra of the Lotus Flower of the Wonderful Dharma,
Know this, has compassion towards all living beings
Because he is my messenger.
Anyone who keeps
The Sutra of the Lotus Flower of the Wonderful Dharma
Should be considered to have given up his pure world and come here
Out of his compassion towards all living beings.
