Yantras are a particular field of mandala imagery that visually represent the harmonic tones of mantras (sacred sounds). By directing our thought patterns to these archetypal planes we invite the essence of these levels to penetrate our minds and thinking. An attunement of individual consciousness with the harmony of universal consciousness develops.

Sri Yantra - or Yantra of Creation - is the most revered of all the Hindu yantras. There is a mysterious beauty that arises in the way that nine diverse triangles interlink to form a state of perfect balance and harmony, and the complementation of the yin and yang ~ creating 43 smaller triangles that define the Sri Yantra.

The Sri Yantra is believed to be the image of the OM mantra, which in the Hindu tradition is understood to be the primordial sound of creation. In his book Rhythms of Vision, Lawrence Blair writes that when the OM is correctly intoned into a tonoscope (a device that transforms sound into a visual representation on a screen), it first produces a circle. As the tone is completed, the circle is filled sequentially with concentric squares, triangles and finally, as the last traces of the "mmm" have died away, the Sri Yantra.
