Tao-sheng Commentary on the Lotus Sutra, p326Thereupon Wonderful-Voice Bodhisattva entered into a samadhi. He did not rise from his seat or make any other movement. By the power of this samadhi, he caused eighty-four thousand lotus flowers of treasures to appear in a place not far from the seat of the Dharma situated on Mt. Gṛdhrakūṭa.
[The bodhisattva Fine Sound] wishes to come soon [to the Sahā world-sphere]. Hence, he first displays the wondrous omen of numerous flowers, so that living beings in this realm may begin to be fascinated and will long for it.
Thereupon Śākyamuni Buddha said to Mañjuśrī, “This Many-Treasures Tathāgata, who passed away a long time ago, will cause him to appear before you all.”
The purpose of making Many Jewels now [appear and] display marks is twofold: first, to show that Many Jewels will come for the sake of the Dharma Blossom; second, to show that the paths of various Buddhas are identical.
