way ［道］ ( bodhi; Chin tao;  dō): The Chinese tao (PY dao) means road, way, method, reason, a moral principle, a doctrine, the source of all things, etc. Lao Tzu, who is said to have lived in the sixth through the fifth century b.c.e., used it to indicate the fundamental principle or the source of the universe. The religious philosophy he helped establish, known in the West as Taoism, emphasizes “nonaction” (Chin wu-wei;  mui), which implies letting things take their natural course. When Buddhism was introduced to China, it was first interpreted and translated using Taoist concepts and terminology. This method of interpretation is known as “matching the meaning” (ke-yi; kakugi). For example, the Sanskrit bodhi, or enlightenment, was rendered as “the way” (tao) and nirvana, as “nonaction.” Use of “the way” or “attaining the way” to mean enlightenment became well established in Buddhist literature.
