threefold Lotus Sutra ［法華三部経］ ( Hokke-sambu-kyō): The Immeasurable Meanings Sutra, the Lotus Sutra, and the Universal Worthy Sutra. The Immeasurable Meanings and Universal Worthy sutras serve respectively as the prologue and epilogue to the Lotus Sutra. In the Immeasurable Meanings Sutra, Shakyamuni states, “In these more than forty years, I have not yet revealed the truth,” thus making clear that his teachings up until this point are provisional. In this context, the Lotus Sutra says, “The World-Honored One has long expounded his doctrines and now must reveal the truth.” The Immeasurable Meanings Sutra also states that all principles and meanings are born from a single Law, thus preparing the way for the Lotus Sutra to reveal that Law. The Lotus Sutra expounds the one Buddha vehicle that enables all people to attain Buddhahood, as well as the Buddha’s original enlightenment in the remote past. The Universal Worthy Sutra emphasizes the necessity of propagating the Lotus Sutra.
