Twice in Kaimoku-shō, Nichiren expresses his determination in the form of vows. Roughly one third of the way into the work he states, “… it is not easy to uphold even a word or phrase of the Lotus Sūtra in the Latter Age of Degeneration. This must be it! I have made a vow that this time I will have an unbending aspiration to buddhahood and never fall back!” (Hori 2002, p. 53) Towards the end of Kaimoku-shō, Nichiren again states his determination in the form of vow or perhaps series of vows to continue to uphold the Lotus Sūtra no matter what; furthermore, he vows to be like a pillar, a pair of eyes, or a great vessel for Japan. I think it could be said that this vow is the real climax of the Kaimoku-shō.

“I have made a vow. Even if someone says that he would make me the ruler of Japan on the condition that I give up the Lotus Sūtra and rely upon the Contemplation of the Buddha of Infinite Life Sūtra for my salvation in the next life, or even if someone threatens me saying that he will execute my parents if I do not say “Namu Amidabutsu,” and no matter how many great difficulties fall upon me, I will not submit to them until a man of wisdom defeats me by reason. Other difficulties are like dust in the wind. I will never break my vow to become the pillar of Japan, to become the eyes of Japan, and to become the great vessel for Japan.” (Hori 2002, pp. 105106 adapted)
