Day 10 concludes Chapter 6, Assurance of Future Buddhahood, and opens Chapter 7, The Parable of a Magic City.
Having last month concluded Chapter 6, Assurance of Future Buddhahood, we open Chapter 7, with the story of Great-Universal-Wisdom-Excellence Buddha.
The Buddha said to the Bhikṣus:
“A countless, limitless, inconceivable, asaṃkhya number of kalpas ago, there lived a Buddha called Great-Universal-Wisdom-Excellence, the Tathāgata, the Deserver of Offerings, the Perfectly Enlightened One, the Man of Wisdom and Practice, the Well-Gone, the Knower of the World, the Unsurpassed Man, the Controller of Men, the Teacher of Gods and Men, the Buddha, the World-Honored One. His world was called Well-Composed; and the kalpa in which he became that Buddha, Great-Form.
“Bhikṣus! It is a very long time since that Buddha passed away. Suppose someone smashed all the earth-particles of one thousand million Sumeru-worlds into ink-powder. Then he went to the east[, carrying the ink-powder with him]. He inked a dot as large as a particle of dust [with that ink-powder] on the world at a distance of one thousand worlds from his world. Then he went again and repeated the inking of a dot on the world at every distance of one thousand worlds until the ink-powder was exhausted. What do you think of this? Do you think that any mathematician or any disciple of a mathematician could count the number of the worlds [he went through]?”
“No, we do not, World-Honored One!”
“Bhikṣus! Now all the worlds he went through, whether they were inked or not, were smashed into dust. The number of the kalpas which have elapsed since that Buddha passed away is many hundreds of thousands of billions of asaṃkhyas larger than the number of the particles of the dust thus produced. Yet I remember [the extinction of] that Buddha by my power of insight as vividly as if he had passed away today.”
The Introduction to the Lotus Sūtra offers this on the topic of previous existences and Three Methods of Expounding the Law:
[Chapter 7, The Parable of a Magic City,] has two distinct parts. The first is a story of the previous existence of a Buddha called Great-Universally-Excelling-Wisdom. The second consists of the parable for which this chapter is named, “The Magic City.” The concept of previous existences is a fundamental teaching in Buddhism. Its rationale is that there must be some prior meaning or conditions before something else can come into existence. (Nothing comes from nothing, and nothing takes place without a cause.) The story of a previous life here refers to a particular incident in the past which has led to the emergence of a present situation—that is, the origin of things. In the Lotus Sutra, Sakyamuni is said to employ three methods of expounding the law: logical explanations, parables, and stories of previous lives.
