Contemplation of the Mind with Daimoku

[T]he “contemplation of the mind” in Nichiren’s teaching is not the introspective meditation on the moment-to-moment activity of one’s (unenlightened) mind, but rather embracing the daimoku, which is said to embody the enlightenment of the eternal Buddha of the origin teaching, that is, the three thousand realms in a single thought-moment in actuality.

“Embracing” the daimoku has the aspects both of chanting and having the mind of faith (shinjin); for Nichiren, the two are inseparable. Faith is also all-inclusive: in the Final Dharma age, it substitutes for the three disciplines of precepts, meditation, and wisdom. “That ordinary worldlings born in the Final Dharma age can believe in the Lotus Sūtra is because the Buddha realm is inherent in the human realm.” Thus the “one thought-moment containing three thousand realms” is also the “single moment of belief and understanding.” In the moment of faith, the three thousand realms of the original Buddha and those of the ordinary worldling are one. This moment of faith corresponds to the stage of myōji-soku. Like that of many medieval Tendai texts, Nichiren’s thought focuses on realizing Buddhahood at the stage of verbal identity, which he understood as the stage of embracing the daimoku of the Lotus Sūtra and taking faith in it.
