lord of teachings ［教主］ ( kyōshu): A Buddha. Lord of teachings often refers to Shakyamuni Buddha, the founder of Buddhism and expounder of its teachings. In Mahayana Buddhism, however, it refers also to numerous Buddhas who dwell in their own lands throughout the universe and preach doctrines to instruct and convert beings. For example, Medicine Master Buddha teaches in the Pure Emerald World in the east, and Amida Buddha in the land of Perfect Bliss in the west. The Buddha who is revered in a particular Buddhist school is usually considered the lord of teachings for that school.
