Not only those sutras preached by Śākyamuni Buddha but also those expounded by seven Buddhas and 1,000 Buddhas in the past, numerous Buddhas from the remotest past, as well as various Buddhas of all the worlds in the universe today are all subordinates to the Chinese character kyō of the Lotus Sūtra. Therefore, the Lotus Sūtra says to Star King Flower Bodhisattva in the 23rd chapter, “Medicine King Bodhisattva,” that just as the sea is larger than any river, Mt. Sumeru is the largest of all the mountains, and the moon is brighter than any star, the Lotus Sūtra is supreme of all the sūtras. Grand Master Miao-lê interprets this saying that the Lotus Sūtra is the best of all the Buddhist scriptures preached in the past, being preached at present, and to be preached in the future. That is to say, all the Buddhist scriptures of all the worlds in the universe are contained in the Chinese character kyō of the Lotus Sūtra.
