QUESTION: I would like to know how great the merit contained in only five Chinese characters of myō, hō, ren, ge, and kyō can be.
ANSWER: The great ocean receives the whole flow of rivers from all over the world; the great earth contains everything including sentient and insentient beings; the wish-fulfilling gem rains all kinds of treasures; the King of the Brahma Heaven controls the whole Triple World (realms of desire, no desire, and non-form). Likewise, the five Chinese characters of myō, hō, ren, ge, and kyō possess the merits of all phenomena. In short, they contain everything in the Ten Realms from hell to the realm of Buddhas, including those that exist in the lands and the lands themselves.
