Firmly Established Practices ［安立行菩薩］ ( Supratishthitachāritra; Anryūgyō-bosatsu): One of the four bodhisattvas who are the leaders of the Bodhisattvas of the Earth. He appears in the “Emerging from the Earth” (fifteenth) chapter of the Lotus Sutra. The chapter says: ”Among these bodhisattvas were four leaders. The first was called Superior Practices, the second was called Boundless Practices, the third was called Pure Practices, and the fourth was called Firmly Established Practices. These four bodhisattvas were the foremost leaders and guiding teachers among all the group.”
According to Tao-hsien’s Supplement to “The Words and Phrases of the Lotus Sutra,” the four bodhisattvas represent the four virtues of a Buddha: true self, eternity, purity, and happiness. Bodhisattva Firmly Established Practices represents happiness.
