A yantra is a geometric diagram used in Hindu and Buddhist traditions, often serving as a tool for meditation and spiritual practice. Typically made of interlocking shapes, such as triangles and circles, yantras symbolize various deities and cosmic principles. They are believed to harness spiritual energy and aid in focusing the mind during meditation. In addition to their spiritual significance, yantras are often used in rituals and ceremonies. Each yantra is associated with specific intentions, such as prosperity or protection, and is often placed in homes or temples. The most famous yantra is the Sri Yantra, which represents the divine feminine energy of the goddess Shakti.
