Handpainted Ganesha Yantra 

YANTRA'S.
Yantra is a mystical diagram used in the Indian religions and philosophy for worship. It is used to help in meditation and for the benefits of its purported occult powers based on Tantric texts and Hindu astrology. It is a type of mandala, which is a spiritual symbol representing the universe.

In classical Sanskrit, the word, yantra, means “instrument,” “apparatus” or “contrivance.” It is derived from the root word, yam, meaning "to support" or "to sustain the essence of an object/concept."

Just as mantras balance the body and mind through sound, yantras provide balance visually. They are geometric and include floral designs. The shapes are believed to have a powerful quieting effect on the mind, and so are used in yogic meditation practice. Yantras are often associated with a particular deity and may be worn as a talisman.
