Tendai Lotus School Teachings, p 48Q: The teachings of the Buddha’s life include all of the Four Teachings. Why are the Five Flavors also established?
A: The Four Teachings are given in reference to the depth or shallowness of capabilities, and the Five Flavors clarify the order of the teaching. The purpose of interpreting all meaning and truth with the Four Teachings and the Five Flavors is to manifest the Lotus Sutra as the climax of the Buddha’s life teachings.
