Yantra is the Sanskrit word for "instrument" or "machine". It can stand for symbols, processes, machinery or anything that has structure and organization. One popular use in the west is as symbols or geometric figures. Traditionally such symbols are used to balance the mind or focus it on spiritual concepts. The act of wearing, depicting, enacting and/or concentrating on a yantra is held to have spiritual or astrological or magical benefits within the tantric dimension of the dharmik traditions.
