Pure Practices ［浄行菩薩］ ( Vishuddhachāritra;  Jōgyō-bosatsu): One of the four leaders of the Bodhisattvas of the Earth, who appear in the “Emerging from the Earth” (fifteenth) chapter of the Lotus Sutra. The Supplement to “The Words and Phrases of the Lotus Sutra” by Tao-hsien, an eighth-century priest of the T’ien-t’ai school in China, says that the four bodhisattvas represent the four virtues of the Buddha’s life—true self, eternity, purity, and happiness. Of these virtues, Bodhisattva Pure Practices represents purity.
