Among the 32 marks of the Buddha, His “Brahma’s voice” is foremost. The king of a country, be it great or small, and such kings as the “Wheel-turning Noble King” partly possess this “Brahma’s voice.” Therefore, a word of the king can govern the country or ruin it. An imperial decree is also in part like “Brahma’s voice.” Ten thousand words of the whole country cannot equal to one word of the king. The books of the Three Emperors and Five Rulers in ancient China are words of minor rulers. It was due to the strength of this “Brahma’s voice” that lesser kings govern small countries, that the King of the Mahābrahman Heaven is attended to by all living beings of the triple world (the realms of desire, form, and non-form), and that the Buddha is attended to by the King of the Mahābrahman Heaven and Indra.
The teachings uttered by the “Brahma’s voice” are all the scriptures of Buddhism to save all living beings. Among the scriptures the Lotus Sūtra in particular is the design of Śākyamuni Buddha uttered through His “Brahma’s voice,” which was written down in Chinese characters. The true intent of the Buddha, therefore, exists in the characters of the Lotus Sūtra. Just as seeds, seedlings, grasses, and rice plants differ in shape though they remain the same in spirit, Śākyamuni Buddha and the characters of the Lotus Sūtra are not the same in shape but they are one in essence. Thus, when you read the letters of the Lotus Sūtra, you must consider yourself in the presence of the living Śākyamuni Buddha.
