In Chapter Nineteen, “Merits of a Teacher of the Dharma,” we read, “When they expound the scriptures of non-Buddhist schools, or give advice to the government, or teach the way to earn a livelihood, they will be able to be in accord with the right teachings of the Buddha” (p. 282). This means that any study of secular issues, such as politics and economics, must be in accord with the cosmic law, which is to say, the Truth expounded in the Sutra. Conversely, the teachings of the Lotus Sutra (The Truth) are applicable to secular studies, such as politics or economics, whose prime objectives are the betterment of everyday life.
