Sri Yantra is a Hindu meditation diagram made up of nine variously sized interlocking, intersecting triangles that form 43 smaller triangles on five concentric levels that represents the cosmos and the human body. That surrounds a central "bindu", which symbolizes the cosmic center. Two concentric circles with eight and sixteen lotus petals respectively circumscribe the main visual. It is all framed by four broken lines symbolizing the earth square, or a temple with four open-to-the-universe doors. Focusing on it brings about non-duality or adviata.
