This conception of the Buddha-nature, and of its realization in ourselves through worship, are consequences of the time-honored theory of the Threefold Personality (tri-kāya) of Buddha. But the characteristic feature in Nichiren’s ideas is that he never was content to talk of abstract truth, but always applied the truth taught to actual life, bringing it into vital touch with his own life. Ethics and metaphysics are never to be separated, but to be united in religion, and religion means a life actually embodying truth and virtue. Truths are revealed and virtues inculcated in the Lotus of Truth, and consequently the true religious life is equivalent to “reading the Scripture by person.” Thus, the essay, which begins with discussions of the metaphysical entity of Buddha-nature, proceeds naturally to a consideration of the Buddhist life, especially as exemplified in Nichiren’s own life.

The Scripture says, “If one preaches to anybody the Lotus of Truth, even just one clause of it, he is, know ye, the messenger of the Tathāgata, the one commissioned by the Tathāgata, and the one who does the work of the Tathāgata.” How, then, can I be anybody else than this one? …
“By all means, awaken faith by seizing this opportunity! Live your life through as the one who embodies the Truth and go on without hesitation as a kinsman of Nichiren! If you are one in faith with Nichiren, you are one of the Saints-out-of-Earth; if you are destined to be such, how can you doubt that you are the disciple of the Lord Śākyamuni from all eternity? There is assurance of this in a word of Buddha, which says: “I have always, from eternity, been instructing and quickening all these beings.” No attention should be paid to the difference between men and women among those who would propagate the Lotus of the Perfect Truth in the days of the Latter Law. To utter the Sacred Title is, indeed, the privilege of the Saints-out-of-Earth. …
