The chapter “Encouragement of Universal Sage Bodhisattva” says that among many disciples of Śākyamuni Buddha, Kāśyapa and Ānanda waited on Him. They were like ministers attending both sides of a king. But this was the Buddha preaching sūtras of the Lesser Vehicle. Among many bodhisattvas, the Bodhisattva Universal Sage and the Bodhisattva Mañjuśrī attended Śākyamuni Buddha, the Lord Teacher, like two ministers attending both sides of a king. During the last eight years of the life of Śākyamuni Buddha, in which He expounded the Lotus Sūtra, so many Buddhas and bodhisattvas, more than dust particles on the earth, gathered from ten quarters in the universe. But strangely, Bodhisattva Universal Sage, one of the attendants of Śākyamuni Buddha, was not found there.

However, when Śākyamuni Buddha was about to finish His preaching by expounding the chapter “Wonderful Adornment King,” Bodhisattva Universal Sage came late from the land of the Jeweled Dignity and Virtue Purity King Buddha, performing hundreds of thousands of pieces of music and accompanied by a countless number of eight kinds of gods and demi-gods. Concerned about the reaction of the Buddha toward his late arrival, the bodhisattva turned pale and obligingly vowed to protect the practicer of the Lotus Sūtra in the Latter Age of Degeneration. Śākyamuni Buddha was pleased and told that it was his obligation to spread the Lotus Sūtra in the whole world. Śākyamuni Buddha thus praised Bodhisattva Universal Sage more cordially than his superiors.
