It is clearly stated in the Lotus Sūtra that the true intent of the Buddha has completely been preached in it. The second chapter on “Expedients” declares, “Now is the time to expound the wisdom of the Buddha.” The sixteenth chapter on “The Life Span of the Buddha” states, “I have always been contemplating how I should lead all people into the Supreme Way, enabling them to become Buddhas promptly.” The twenty-first chapter on “Divine Powers of the Buddha” states, “In sum, the teachings of the Buddha are all revealed and clearly expounded in this sūtra.”

These statements of the Buddha clearly show that the enlightenment of Śākyamuni Buddha is revealed in this sūtra without reservation. Moreover, the Buddha of Many Treasures and Buddhas in manifestation in the worlds all over the universe gathered together in the courtyard on Mt. Sacred Eagle to validate the words of Śākyamuni Buddha: “Of all the Buddhist scriptures, which have already been preached, now being preached and will be preached in the future…” deciding that no sūtras are as difficult to understand and put faith in as the Lotus Sūtra, supreme of all scriptures.
