The character myō of the Lotus Sūtra is likened to the sunshine of spring through summer, and blossoming and bearing fruits mean aspiration for and attainment of Buddhahood by those people. Bodhisattva Nāgārjuna says in his Great Wisdom Discourse that it is “like a great medicine master turning poison into medicine.” This is his explanation of how virtuous “myō” of the Lotus Sūtra was. Grand Master Miao-lê says also that the Lotus Sūtra is named “myō” because it was able to heal all the sick people with obstinate diseases that had not been cured by any other sūtras.
