Though the teaching I am now propagating seems limited, it is extremely profound. That is because it goes deeper than the teaching expounded by T’ien-t’ai, Dengyō, and others. It is the three important matters1 in the “Life Span” chapter of the essential teaching. Practicing only the seven characters of Nam-myoho-renge-kyo seems limited, but since they are the master of all the Buddhas of the three existences, the teacher of all the bodhisattvas in the ten directions, and the guide that enables all living beings to attain the Buddha way, it is profound.
The sutra states, “The wisdom of the Buddhas is infinitely profound and immeasurable.”2 It refers to “the Buddhas” here in the sense of all Buddhas throughout the ten directions in the three existences, from the Thus Come One Mahāvairochana of the True Word school and Amida of the Pure Land school to the Buddhas and bodhisattvas of all schools and all sutras, all Buddhas of the past, future, and present, and the present Thus Come One Shakyamuni. And the sutra speaks of the wisdom of all those Buddhas.
What is meant by this “wisdom”? It is the entity of the true aspect of p.318all phenomena, and of the ten factors of life that lead all beings to Buddhahood. What then is that entity? It is Nam-myoho-renge-kyo. A commentary states that the profound principle of the true aspect is the originally inherent Myoho-renge-kyo.3 We learn that that true aspect of all phenomena is also the two Buddhas Shakyamuni and Many Treasures [seated together in the treasure tower]. “All phenomena” corresponds to Many Treasures, and “the true aspect” corresponds to Shakyamuni. These are also the two elements of reality and wisdom. Many Treasures is reality; Shakyamuni is wisdom. It is the enlightenment that reality and wisdom are two, and yet they are not two.
