The Lotus Sutra is very nice sounding theory. It is theory and remains theoretical until you are able to understand it by faith. Knowing something in our brains, knowing the theory, may be helpful in some aspects of life, but in Buddhism, and especially concerning the teachings in the Lotus Sutra, what is important is the actualization in your life. This brings us back to the opening words of Chapter XVI, the statement by the Buddha that understanding the truth of the Lotus Sutra comes from faith.
