A yantra is a geometrical diagram primarily originating from the Tantric traditions of Indian religions. These diagrams are utilized for the worship of deities in both temples and domestic settings, as well as serving as aids during meditation. They are also employed to provide benefits believed to be granted by occult powers based on Hindu astrology and tantric texts.
In addition to their spiritual functions, yantras are used to adorn temple floors due to their aesthetic and symmetric qualities. Specific yantras are traditionally associated with particular deities or specific types of energies intended for the accomplishment of various materialistic or spiritual tasks and vows. They serve as primary tools in certain sadhanas performed by a sadhaka, or spiritual seeker.
Yantras hold significant importance across several major religions, including Hinduism, Jainism, and Buddhism.
