After entrusting the essential dharma of five characters to the bodhisattvas who appeared from underground, the Buddha ascended from the Stupa of Treasures. Standing in the sky, the Buddha tapped the heads of Mañjuśrī, Avalokiteśvara, the King of the Brahma Heaven, Indra, the sun and moon, the Four Heavenly Kings and others three times, and entrusted them with the expanded and concise teachings of the Lotus Sūtra (though without the essential dharma) as well as all the sūtras preached before and after the Lotus Sūtra. This was for the sake of saving the people in the 2,000-year period of the Ages of the True Dharma and the Semblance Dharma. Thereafter, when the Buddha preached the Nirvana Sūtra, He again expounded the Lotus as well as pre-Lotus sūtras, entrusting them to such great bodhisattvas as Mañjuśrī. This was the preaching regarding the benefit of gleaning after the harvest of the Lotus Sūtra.

Thus what the Buddha transmitted was not the same, so the task of propagation after the death of the Buddha was limited according to the content of transmission. Accordingly Kāśyapa, Ānanda and others spread only the Hinayāna sūtras without expounding the Mahāyāna sūtras. Nāgārjuna, Asaṅga and others spread the provisional Mahāyāna sūtras without preaching the One Vehicle true teaching of the Lotus Sūtra. Even though they preached the Lotus Sūtra, they merely suggested its teaching, or they preached merely a part of the theoretical section without discussing the beginning and ending of the Buddha’s guidance.

Appearing in this world as the avatars of Avalokiteśvara and Medicine King Bodhisattva, Grand Masters Nan-yüeh and T’ien-t’ai expounded both the Hinayāna and Mahāyāna sūtras, provisional and true teachings, the theoretical and essential sections of the Lotus Sūtra, as well as such doctrines as the beginning and ending of the Buddha’s guidance and the eternal relationship between the Buddha and His disciples. Moreover, they advocated the theory of “sūtras which had been preached, are being preached, and will be preached,” claiming that the Lotus Sūtra was supreme among all the holy teachings preached in the lifetime of the Buddha. Their critical classification of teachings is superior to those of commentators in India and many masters in China. Tripiṭaka masters of both old and new translations do not equal to Nan-yüeh and T’ien-t’ai at all. Founders of both exoteric and esoteric Buddhist schools cannot compete with them. The two grand masters, however, were still basing themselves on the whole or parts of the Lotus Sūtra without expounding its essence, the five characters. Although they themselves knew it, they did not convey this to others. It was solely because they correctly remembered what was entrusted to them and respected what the Buddha had in mind.
