Guru (Devanagari गà¥à¤°à¥) is a Sanskrit term for "teacher" or "master", especially in Indian religions. The Hindu guru-shishya tradition is the oral tradition or religious doctrine or experiential wisdom transmitted from teacher to student. In the United States, the meaning of "guru" has been used to cover anyone who acquires followers, especially by exploiting their naiveté, due to the inflationary use of the term in new religious movements.
