“The Sri Yantra is a configuration of nine interlocking triangles, surrounded by two circles of lotus petals with the whole encased within a gated frame, called the “earth citadel”. The nine interlocking triangles centered around the bindu (the central point of the yantra) are drawn by the superimposition of five downward pointing triangles, representing Shakti ; the female principle and four upright triangles, representing Shiva ; the male principle. The nine interlocking triangles form forty three small triangles each housing a presiding deity associated with particular aspects of existence.” – Source Tantra-kundalini.com
