[I]n Chapter XV we have a transition from Buddhist practices, including the Lotus Sutra, of being either solely spiritual or intellectual activities. In this chapter what comes out is the practice of the Lotus Sutra is one of action and involvement in the material world. It isn’t simply about self-improvement but about carrying our practice into the world where we work, live, and play. The value of the practice is only realized when we can manifest it in our lives.
