The Sacred Title of the Lotus had established this standard for oral utterance, and now [Nichiren] proposed to furnish the same for spiritual introspection through visualization, because the vast universe, with all its beings, was nothing but an extension, an outward manifestation of everyone’s Buddha-nature. The visualized standard was made for the purpose of impressing one’s soul with the true and everlasting nature of its own identity with the eternal Buddha and that of every other existence. The Supreme Being meant a perfect union of the individual and the world, the oneness of the Buddha-nature and its inexhaustible manifestations.
