The Sri Yantra or “holy instrument” is formed by nine interlocking triangles that surround and radiate out from a central point or “bindu”, symbolizing the junction point between the physical universe and its unmanifest source. Four isosceles triangles with the apices upwards, representing the Masculine and five isosceles triangles with the apices downward, symbolizing the feminine. Thus the Sri Yantra represents the union of Masculine and Feminine. These nine triangles are of various sizes and intersect with one another. In the middle is the power point, the invisible, elusive centre from which the entire figure and the cosmos expand. The triangles are enclosed by two rows of (8 and 16) petals, representing the lotus of creation and reproductive vital force. Together the nine triangles are interlaced in such a way as to form 43 smaller triangles in a web symbolic of the entire cosmos or a womb symbolic of creation. This is surrounded by a lotus of eight petals, a lotus of sixteen petals, and an earth square resembling a temple with four doors.
