The Lotus Sutra is the true teaching because the Buddha Sakyamuni preached it from the bottom of his heart exactly as he was enlightened. Other sutras were taught according to listeners’ level of understanding. The Buddha teaches righteousness. The chanting of the sutra will lead us to righteousness unconsciously. For example, the creeping mugwort grass among the hemp will grow straight, or the body of a snake will become straight if it goes into a straight pipe, or if one has good friends, his attitudes will become good. Likewise, one who believes in the Lotus Sutra will attain Buddhahood.
