Nath is a term that can refer to various subjects, including a name, a place, or a concept in different cultures. In some contexts, it is used as a surname or given name, often found in regions like India and Nepal. The name is derived from the Sanskrit word "natha," meaning "lord" or "protector." In Hindu mythology, Nath can also refer to the Nath Sampradaya, a spiritual tradition that emphasizes the worship of Lord Shiva and the practice of yoga. This tradition has produced many notable saints and philosophers, contributing to the rich tapestry of Indian spirituality.
