Shingon Buddhism further insists that although the Lotus Sutra knows theories about the 3,000 realms of existence, it doesn't know rituals, including symbols and words of truth ("shingon" in Japanese), and that the Great Sun Buddha Sutra, which teaches rituals along with theories, is therefore superior to the Lotus Sutra.
