After I finished The Distance from the Buddha Realm to Hell, I wanted to reinforce my understanding of the foundation of this teaching. I went back to Gemini Notebook and opened the Nichiren Notebook. I wrote:
Provide the source for your statement: You do not manifest your inherent Buddha-nature simply by intellectually knowing it is there. Rather, it must be actively polished and given concrete, relational expression through your daily behavior, your faith, and your vocal practice of the Daimoku.
Here’s the response:
While this statement is a contemporary theological synthesis of the core doctrines in the notebook, its direct claims are deeply anchored in several of Nichiren Shōnin’s authenticated letters and the scholarly analyses of his relationship to medieval Tendai philosophy.
You can trace the distinct components of this statement to the following specific sources in the library:
1. The Danger of Passive “Intellectual Knowing”
The opening of the statement—criticizing the idea that one can manifest Buddhahood simply through passive, intellectual acknowledgment—is grounded in Nichiren’s sharp warnings against “self-conceit” (arrogance).In his letter A Reply to Lord Ueno (Ueno-dono Gohenji), Nichiren Shōnin quotes the Tendai commentator Miao-lo to warn against the spiritual traps of a purely theoretical understanding of immanent enlightenment:
“When people with evil passions are told that they will become Buddhas as they are, they will neglect to cultivate the roots of goodness or to amend their self-conceit… both are similar in assuming that the Buddha and people are the same, and they are disgraceful who do not reflect upon themselves.”
This is further supported by the historical analysis of Jacqueline I. Stone. Scholars note that while medieval Tendai original enlightenment (Hongaku) thought often remained “theoretical” and “abstract”—focusing on the first stage of the six identities, identity in principle (ri-soku)—Nichiren Shōnin insisted on a “practical Buddhism” that demanded active engagement. He shifted the focus to verbal identity (myōji-soku), which represents the actual starting point of vocal practice and faith.
As detailed in The Indestructible Vow, this active shift was a direct response to the moral laxity of the era, transforming a passive ontological status into an active, lived commitment.
2. The Necessity of Active “Polishing” and Chanting
The middle of the statement—asserting that the mind must be “actively polished” through the vocal practice of the Daimoku—comes directly from Nichiren’s famous early treatise, On Becoming a Buddha in One Lifetime (Isshō Jōbutsu Shō).Nichiren Shōnin explains that the deluded mind and the enlightened mind are the same mirror, but the dust of fundamental ignorance must be cleared away through daily practice:
“Even right now, the deluded mind in a single thought-moment of ignorance is an unpolished mirror. But if one polishes it, it will surely become the bright mirror that is the true suchness of the Dharma nature. Profoundly arouse the mind of faith and day and night, morning and evening, polish [the mirror of the mind] without neglect. How should one polish it? Simply chanting Namu-myōhō-renge-kyō is what is called ‘polishing.'”
This insistence on active discipline is reinforced in the Shoho Jissō Shō, where the writings declare:
“Learn and practice to strengthen your faith. Without learning and practicing there is no Buddhism. To learn and to practice are a part of faith.”
3. Concrete, Behavioral, and Relational Expression
The final portion of the statement—requiring that this inherent nature be given concrete, relational expression through daily behavior—is grounded in A Reply to My Lady, the Nun Myōhō (Myōhō-ama Gozen Gohenji).To demonstrate that enlightenment must be visible in one’s actions, Nichiren Shōnin states:
“The person who chants Namu-myōhō-renge-kyō is a Buddha. His body is the dharma-body of the Buddha; his mind, the reward-body of the Buddha; and his behavior, the manifestation-body of the Buddha.”
By identifying a practitioner’s daily behavior as the “manifestation-body” (niryāna-kāya) of the Buddha, the teachings close the loop: your inner faith is not an abstract theory, but a dynamic, compassionate force that must actively transform your conduct, your relationships, and your environment.
