A guru is a teacher or guide, often in a spiritual or philosophical context. The term originates from the Sanskrit word meaning "heavy" or "weighty," signifying someone with significant knowledge or wisdom. Gurus are commonly associated with various traditions, including Hinduism, Buddhism, and Sikhism, where they play a crucial role in imparting teachings and guiding followers on their spiritual journeys. In modern contexts, the term "guru" has expanded to include experts in various fields, such as business, health, or technology. These individuals are often sought after for their insights and advice, helping others navigate challenges and achieve personal or professional growth.
