Day 26 concludes Chapter 21, The Supernatural Powers of the Tathāgatas, includes Chapter 22, Transmission, and introduces Chapter 23, The Previous Life of Medicine-King Bodhisattva.
Having last month considered Gladly-Seen-By-All-Beings’ ultimate gift to the Buddha, we conclude today’s portion of Chapter 23, The Previous Life of Medicine-King Bodhisattva.
In his next life, he appeared again in the world of Sun-Moon-Pure-Bright-Virtue Buddha. It was in the house of King Pure-Virtue [in that world] that he suddenly appeared with his legs crossed [in the person of the son of the king] . He said to his father in a gāthā:
Great King, know this, [in my previous existence]
I walked about this world, and at once obtained
The samadhi by which I can transform myself
Into any other living being. With a great endeavor,
I gave up my own dear body.“Having sung this gāthā, he said to his father, ‘Sun-Moon-Pure-Bright-Virtue Buddha is still alive. [In my previous existence] I made offerings to him, and obtained the dhārāṇis by which I can understand the words of all living beings. I also heard from him the eight hundred thousands of billions of nayuta of kankaras of bimbaras of asaṃkhyas of gāthās of this Sūtra o the Lotus Flower of the Wonderful Dharma. Great King! Now I will make another offering to the Buddha.’
“Having said this, he sat on a platform of the seven treasures. The platform went up to the sky seven times as high as the tala-tree. He came to the Buddha [who was staying in the sky], worshipped the feet of the Buddha with his head, joined his ten fingers [and palms] together, and praised the Buddha in a gāthā:
Your face is most wonderful.
Your light illumines the worlds of the ten quarters.
I once made offerings to you.
Now I have come to see you again.
While not specific to this section, here’s something Nichiren wrote on the main meaning of the “Medicine King Bodhisattva” chapter:
As for the main meaning of the “Medicine King Bodhisattva” chapter, it is in the seventh fascicle of the sūtra and is the 23rd of the 28 chapters. The first fascicle of the Lotus Sūtra includes the “Introductory” and “Expedients” chapters, the former being the introduction to the 28 chapters. The eight chapters from the “Expedients” to the “Assurance of Future Buddhahood of Learners and Adepts” chapters chiefly clarifies the attainment of Buddhahood by the Two Vehicles of śrāvaka and Pratyekabuddha and secondly explains the attainment of Buddhahood by bodhisattvas and ordinary people.
The five chapters, “The Teacher of the Dharma,” “The Appearance of the Stupa of Treasures,” “Devadatta,” “Encouragement for Upholding This Sūtra,” and “Peaceful Practices” chapters, expound the way ordinary people in the Latter Age of Degeneration should practice the eight chapters following the second “Expedients” chapter. Also, the 15th “Appearance of Bodhisattvas from Underground” chapter is the introductory to the 16th “Life Span of the Buddha” chapter. The 12 chapters beginning with the 17th chapter, “Variety of Merits,” explain mainly how ordinary people in the Latter Age of Degeneration should practice the “Life Span of the Buddha” chapter, while in the second place they also preach how to practice the eight chapters beginning with the “Expedients” chapter. Accordingly, this “Medicine King Bodhisattva” chapter explains the way to practice the eight chapters following the “Expedients” chapter as well as the “Life Span of the Buddha” chapter.
