When the Lotus Sūtra was preached on Mt. Sacred Eagle, King Ajātaśatru, the most unfilial man in the world, attended the meeting; even Devadatta, who had abused the True Dharma throughout his life, was guaranteed to be Tennō (Heavenly King) Buddha in the future. Furthermore, a dragon girl, though females were considered incapable of becoming a King of the Brahma Heaven, an Indra, a King of Devils, a Wheel-turning Noble King, or a Buddha, became a Buddha without changing her dragon-body. Attainment of Buddhahood by men of the Two Vehicles, and those with fixed natures who had been considered definitely incapable of becoming Buddhas, was as wondrous as a toasted seed germinating, flowering and bearing fruit. When Śākyamuni Buddha’s “attaining Enlightenment in the eternal past” was revealed, the audience was so astonished as to wonder how a hundred-year old man could be the son of a twenty-five year old man. The “3,000 existences contained in one thought” doctrine explained that unenlightened beings in the Nine Realms and enlightened ones in the Realm of the Buddha are one and inseparable, opening the way for the unenlightened to attain Buddhahood. Therefore, each letter of this sūtra represents a wish-fulfilling gem that pours out 10,000 treasures; each phrase of it is the seed of Buddhahood. The preaching of these most profound teachings was not done because of the capacity of the audience, their intelligence to understand or faith to uphold them. It was because the time was ripe. The Lotus Sūtra, chapter 2 on “Expedients,” therefore says: “Now is the time to expound the Mahāyāna teaching definitely.”
