Selection Source: Dialogue on [Wisdom of] the Lotus Sutra, #28:
Establish a life of Eternal, Indestructible Happiness, Living
Buddhism, April 1998, pp. 32-3

Ikeda: The ten factors are also termed the true entity of the ten
factors. The substance of the true entity is none other than Myoho-
renge-kyo itself. The factors of “inherent cause” and “latent
effect,” along with the other eight factors, exist in one’s life at
each moment. This is the simultaneity of cause and effect. This
simultaneity is the marvelous Law of the lotus that we all are
entities of that Law.

“All phenomena” in the phrase “the true entity of all phenomena”
indicates the Ten Worlds. While the phenomena of the universe are
infinite, they are all included in the beings and environment of the
Ten Worlds. All phenomena of the Ten Worlds are the true entity;
that is, they are all entities of the Mystic Law. That is the
meaning of the true entity of all phenomena. …

Ikeda: The true entity accords with the dynamic life of the
universe, without beginning or end. The true entity of all
phenomena reveals the Law through which all beings in the Ten Worlds
can equally attain Buddhahood. This is ichinen sanzen of the
theoretical teaching.
