teacher of the true effect ［本果妙の教主］ ( honga-myō-no-kyōshu): In Nichiren’s teachings, Shakyamuni Buddha. In the “Life Span” (sixteenth) chapter of the Lotus Sutra, Shakyamuni reveals the true effect, the Buddhahood he attained numberless major world system dust particle kalpas ago. He alludes to the cause of that enlightenment only with the words “Originally I practiced the bodhisattva way,” and does not clarify the teaching or Law that he practiced to attain Buddhahood. Shakyamuni Buddha is called the teacher of the true effect because he revealed his original enlightenment as a result already achieved—as an effect—and did not specify its cause. Nichiren defined the true cause that enabled Shakyamuni and all other Buddhas to attain enlightenment as the Law of Nam-myoho-renge-kyo; he is therefore called the teacher of the true cause.
