Grand Master Miao-lê further explained in his Annotations on the Words and Phrases of the Lotus Sūtra, “Wise men know things in advance as a snake knows that it is a snake.” The meaning of these words in the Lotus Sūtra and annotations by T’ien-t’ai and Miao-lê are clear, that is to say, nobody had ever seen or heard of those bodhisattvas from the earth after Śākyamuni’s enlightenment under the bodhi tree till today, either in this world or in any of the worlds in the universe.
So the Buddha answered the question of Bodhisattva Maitreya: “Maitreya! It was I who taught and guided those great bodhisattvas whom you said you had never seen. After I attained perfect enlightenment in this Sahā World, I taught, guided, and controlled them, and encouraged them to aspire for enlightenment.” He continued, “After I sat in meditation under the bodhi tree near the town of Gayā and was able to attain perfect enlightenment, I taught and guided them, while preaching the supreme dharma and caused them to aspire for enlightenment. Now they have all been proceeding to the highest enlightenment without falling back I have taught and guided them since the eternal past.”
Then Bodhisattva Maitreya and other great bodhisattvas began to doubt the Buddha. At the time the Flower Garland Sūtra was preached, numerous great bodhisattvas such as Dharma Wisdom gathered. While wondering who they were, Maitreya and others were told by Śākyamuni Buddha, apparently to their satisfaction, that Dharma Wisdom and other great bodhisattvas were Śākyamuni’s “good friends.” The same thing happened to those great bodhisattvas who gathered together at Daihōbō where the Sūtra of the Great Assembly was preached, and to those who gathered at Lake White Heron upon the preaching of the Wisdom Sūtra. The great bodhisattvas appearing from underground now, however, seemed incomparably superior to them, and it appeared probable that they were teachers of Śākyamuni Buddha. Nevertheless, the Buddha declared that it was He who caused them to aspire for enlightenment, as if the Buddha taught and guided immature people as His disciples. It was only natural, therefore, that Bodhisattva Maitreya and others had serious doubts about Śākyamuni Buddha.
