The Lotus Sūtra is called “Zui-jii,” namely it expounds the true mind of the Buddha. Since the Buddha’s mind is so great, even if one does not understand the profound meaning of the sūtra, one can gain innumerable merits by just reading it. Just as a mugwort among hemp plants grows straight and a snake in a tube straightens itself, if one becomes friendly with good people, one’s mind, behavior, and words become naturally gentle. Likewise, the Buddha thinks that those who believe in the Lotus Sūtra become naturally virtuous.
