Day 10 concludes Chapter 6, Assurance of Future Buddhahood, and opens Chapter 7, The Parable of a Magic City.
Having last month considered how Great-Universal-Wisdom-Excellence Buddha waited 10 kalpas for the Dharma of the Buddhas to come into his mind, we meet the 16 sons
“Bhikṣus! At the end of the period of ten small kalpas, the Dharma of the Buddhas came into the mind of Great-UniversalWisdom-Excellence Buddha. Now he attained Anuttara-samyak-saṃbodhi. Before he left home, he had sixteen sons. The first son was called Accumulated-Wisdom. Each of the sons had various playthings. When the sons heard that their father had attained Anuttara-samyak-saṃbodhi, they gave up the playthings, left home, and came to that Buddha.
“[When they were leaving home,] their mothers saw them off, weeping. Not only the wheel-turning-holy-king, who was their grandfather, but also one hundred ministers and hundreds of thousands of billions of subjects surrounded and followed the princes, wishing to come to the place of enlightenment, to see GreatUniversal-Wisdom-Excellence Tathāgata, to make offerings to that Buddha, respect him, honor him, and praise him.
“Having come [to that Buddha], the princes worshipped him at his feet with their heads, walked around him, joined their hands together towards him with all their hearts, looked up at the World Honored One, and praised him in gāthās:
In order to save all living beings,
You, the World-Honored One,
Who have great powers and virtues,
[Made efforts] for many hundreds of millions of years.
Now you have become a Buddha.
You have finally fulfilled your vows. Congratulations!You, the World-Honored One, are exceptional.
When you were sitting,
You were quiet and peaceful.
You did not move your body, hands or feet
For ten small kalpas.Your mind was tranquil, not distracted.
You have finally obtained tranquil extinction.
You now dwell peacefully in the Dharma-without-āsravas.Seeing that you have peacefully attained
The enlightenment of the Buddha,
We, too, have obtained benefits.
Congratulations! How glad we are!
All living beings are suffering.
Being blind, they have no leader.
They do not know how to stop suffering,
Or that they should seek emancipation.
In the long night fewer people go to heaven,
And more people go to the evil regions.
They go from darkness to darkness, and do not hear
Of the names of the Buddhas.You are the Most Honorable One.
You have obtained the peaceful
Dharma-without-āsravas.
Not only we but also all gods and men
Will be able to obtain the greatest benefit.
Therefore, we bow and devote ourselves to you,
The Most Honorable One.
Nichiren writes on the 16 princes and the Buddhas they became:
The seventh chapter on “The Parable of a Magic City” of the Lotus Sūtra states that the Great Universal Wisdom Buddha had been the king of a country with 16 princes before entering the priesthood; when the king became a Buddha, his 16 princes awakened aspiration for Buddhahood and became novices. Meanwhile the 16 novices grew to be 16 bodhisattvas, preaching the Lotus Sūtra as their father Buddha had taught them and planting the seed of Buddhahood in all the people in the Sahā World. These 16 bodhisattvas all attained Buddhahood, the seventh chapter continues, and they became 16 Buddhas, the first of whom was Akṣobha Buddha, the ninth was Amitābha Buddha, and the sixteenth was Śākyamuni Buddha. Akṣobha Buddha has connection with the world to the east, Amitābha (Buddha of Infinite Life) is connected to the world of the west, and only Śākyamuni Buddha has a karmic relationship with this Sahā World. Each of these Buddhas is equipped with the three benefits of guidance (sowing, maturing, and harvesting) and the three virtues (of lord, master and parents), but both Akṣobha and Amitābha Buddhas are provisional Buddhas who appeared in the world to preach expedient teachings. Therefore, they have neither the three benefits nor the three virtues in the true sense of the word. In other words, their benefits and virtues are recognized only in term of their guidance of the people in their respective worlds, whereas the Eternal Buddha Śākyamuni is perfectly equipped with the three benefits and three virtues.
