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.
There were eight thousand Bodhisattvas who had just resolved to aspire [for Anuttara-samyak-saṃbodhi] in this congregation. They thought, ‘As far as we have heard, even great Bodhisattvas have never been assured of their future Buddhahood. Why have these Śrāvakas been so assured?’
Thereupon the World-Honored One, seeing what the Bodhisattvas had in their minds, said to them:
“Good men! Ānanda and I resolved to aspire for Anuttara-samyak-saṃbodhi under the Void-King Buddha at the same time [in our previous existence]. At that time Ānanda always wished to hear much while I always practiced strenuously. Therefore, I have already attained Anuttara-samyak-saṃbodhi[, but he has not yet]. Now he protects my teachings. He also will protect the store of the teachings of future Buddhas, teach Bodhisattvas, and cause them to attain [Anuttara-samyak-saṃbodhi], according to his original vow. Therefore, now he has been assured of his future Buddhahood.”
This month the Nichiren Buddhist Sangha of the San Francisco Bay Area discussed Chapter 9. It is a fine discussion but for me the discussion of the chapter underscores something stressed in the Sutra of Innumerable Meanings:
“O you of good intent! This sutra can be likened to a single seed from which a thousand million seeds result. And each of these seeds, in turn, also results in a thousand million in number. In this way, the production of seeds is limitless in measure. So it is also with this sutra—it is a single teaching that gives rise to a hundred thousand meanings, and each one of these, in turn, produces a thousand million in number. In this way, meanings are produced to an unlimited and boundless extent.”
In the Nichiren Buddhist Sangha of the San Francisco Bay Area discussion of Chapter 9 there is a lot of discussion about practice and in particular the perils of becoming disheartened if your personal practice falls short of your goal.
While it is important to remember that a single Daimoku is the equivalent of reciting the entire Lotus Sutra, I think the point Chapter 9 is making is that just knowing stuff is not enough. You have to put that knowledge to work. In the above quote from today’s portion of Chapter 9, we learn that Śākyamuni and Ananda both aspired for enlightenment under the Void-King Buddha, but Ananda was too focused on learning and neglected his practice. In the future, he will protect the store of the teachings of future Buddhas, just as he does now, but he will also teach Bodhisattvas, and that will be how he becomes a Buddha named Mountain-Sea-Wisdom-Supernatural-Power-King.
