This batik work shows three yantras on different backgrounds with red symbolizing energy yellow denoting bhakti and white purity. The deity is given shape by the yantra in which its presence during worship is laid out in a precise linear diagram within a polygon. It has around its center several concentric primal shapes such as triangles, circles, rings of lotus petals etc. The yantra's periphery is a square enclosure with four sacred doors opening towards the four cardinal points. The centrifugal yantras are conceived as sacred dwelling in which the presiding deity takes up residence.
The yantra is the most dynamic cosmic symbol and is always used in conjunction with mantras or mystical sound units that correspond to the deity's subtle form. Yantras are also placed in foundation of temple sanctums and used as compositional diagrams in the execution of sculptural images adorning temple walls.
