Yantra (यन्त्र) is a mystical diagram, mainly from the Tantric traditions of the Indian religions. They are used for the worship of deities in temples or at home; as an aid in meditation; used for the benefits given by their supposed occult powers based on Hindu astrology and tantric texts. Yantras are usually associated with a particular deity and are used for specific benefits, such as: for meditation; protection from harmful influences; development of particular powers; attraction of wealth or success, etc. They are often used in daily ritual worship at home or in temples, and sometimes worn as a talisman.
