Now, ignoring false ideas of later commentators in India and mainstream interpreters and annotators in China and Japan, I devotedly open the fundamental sūtras and commentaries, and see that of all sūtras expounded by the Buddha in fifty years, the most important teaching is expounded in the “Teacher of the Dharma” chapter of the Lotus Sūtra, declaring that of all sūtras preached in the past, being preached at present, and will be preached in the future, the Lotus Sūtra is supreme.
