The Annotations to the Words and Phrases of the Lotus Sūtra, fascicle 6, states: “Although various sūtras claim to be the king of sūtras, they do not preach as the Lotus Sūtra does that they are superior to all the sūtras preached in the past, being preached at present and will be preached in the future. You should know for certain that those sūtras preached before the Lotus Sūtra are those preaching the perfect and distinct teachings combined (Flower Garland Sūtra); preaching merely tripiṭaka (Hinayāna) teaching (Āgama sūtras); comparing the tripiṭaka, common, distinct and perfect teachings (Hōdō sūtras); and preaching the perfect teaching tinged with the common and distinct teachings (Wisdom Sūtra).” The Profound Meaning of the Lotus Sūtra, fascicle 3, states, “The tongue will be inflamed in the mouth.” Elaborating on this, the Commentary on the Profound Meaning of the Lotus Sūtra declares: “The Lotus Sūtra is supreme of all the sūtras preached in the past, being preached now, and to be preached in the future. If you harbor any doubts about this, your tongue will be inflamed in this present life and you will suffer for aeons for committing the sin of slandering the True Dharma. … You will be remonstrated by the Buddha for all time.”
