Day 11 continues Chapter 7, The Parable of the Magic City.

The entire day is spent with the reaction to the light of Great-Universal-Wisdom-Excellence Buddha’s enlightenment:

The Buddha said to the bhikṣus:

“When Great-Universal-Wisdom-Excellence Buddha attained Anuttara-samyak-saṃbodhi, five hundred billion Buddha-worlds in each of the ten quarters quaked in the six ways, and all those worlds, including those intercepted from the brilliant rays of light of the sun and the moon by the neighboring worlds, were illumined [by great rays of light], and the living beings of those worlds were able to see each other for the first time. They said to each other, ‘How did you appear so suddenly?’ “

The Brahman-heavenly-kings of each of the five hundred billion worlds of each of the 10 directions each realize something is up.

Let us go even to the end of one thousand billion worlds,
And find the place from where this light has come.
A Buddha may have appeared somewhere in the universe
In order to save the suffering beings.

Heavenly kings from each of the 10 directions descend on the Well-Composed World of Great-Universal-Wisdom-Excellence Buddha to ask the Buddha to turn the wheel of the Dharma:

Most Honorable of Gods and Men!
Turn the wheel of the unsurpassed Dharma,
Beat the drum of the Great Dharma,
Blow the conch-shell horn of the Great Dharma,
Send the rain of the Great Dharma,
And save innumerable living beings!
Devoting ourselves to you, we beg you.
Resound your profound teaching!

And as the Heavenly kings arrive they find Great-Universal-Wisdom-Excellence Buddha’s sixteen sons begging the Buddha to turn the wheel of the Dharma.
