Regarding the Chinese character “myō (wonderful),” the Lotus Sūtra states in chapter 10, “The Teacher of the Dharma,” that this sūtra opens the gate to the expedient teachings expounded in various sūtras and reveals the seal of the truth. Grand Master Chang-an interprets this in the “Preface” in the first fascicle of the Profound Meaning of the Lotus Sūtra that the Buddha opened up the door to the storehouse to disclose the valuables hoarded up in it, which was called myō. Grand Master Miao-lê further explains this in the first fascicle of his Commentary on the Profound Meaning of the Lotus Sūtra that to disclose means to open up. Contemplating on them, I should say, ” myō” means to “open up.”
