Day 31 covers Chapter 27, King Wonderful-Adornment as the Previous Life of a Bodhisattva.
Having last month witnessed the king and queen and their two sons and retainers set off to visit the Buddha, we see Cloud-Thunderpeal-Star-King-Flower-Wisdom Buddha expound the Dharma and hear the prediction for the king.
“Thereupon the Buddha expounded the Dharma to the king, showed him the Way, taught him, benefited him, and caused him to rejoice. The king had great joy. The king and queen took off their necklaces of pearls worth hundreds of thousands, and strewed the necklaces to the Buddha. The necklaces flew up to the sky [seven times as high as the tala-tree], and changed into a jeweled platform equipped with four pillars. On the platform was a couch of great treasures, and thousands of millions of heavenly garment were spread [on the couch]. The Buddha [went up,] sat cross-legged [on the couch], and emitted great rays of light. King Wonderful-Adornment thought, ‘The Buddha is exceptional. He is exceedingly handsome. He has the most wonderful form.’
“Thereupon Cloud-Thunderpeal-Star-King-Flower-Wisdom Buddha said to the four kinds of devotees, ‘Do you see this King Wonderful-Adornment standing before me with his hands joined together, or not? This king will become a bhikṣu under me, strenuously study and practice the various ways to the enlightenment of the Buddha, and then become a Buddha called Sala-Tree-King in a world called Great-Light in a kalpa called Great-Height-King. Sala-Tree-King Buddha will be accompanied by innumerable Bodhisattvas and Śrāvakas. The ground of his world will be even. [King Wonderful-Adornment) will have these merits.’
