Sri Yantra

The Shri Yantra or Sri Chakra of Tripura Sundari is a yantra or mandala formed by nine interlocking triangles surrounding a dot in the cetner called a bindu. Four of these triangles are orientated upright representing Shiva or the Masculine. Five of these triangles are inverted triangles represent Shakti or the Feminine. Because it is composed of nine triangles, it is also known as the "navayoni chakra".
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. Together they express Advaita-ism or non-duality. This is surrounded by a lotus of eight petals, a lotus of sixteen petals, and an earthsquare resembling a temple with four doors.
The Shri Chakra is also known as the "nava chakra" because it can also be seen as having nine levels. Each level corresponds to a mudra, a yogini, and a specific form of the deity Tripura Sundari along with her mantra. These levels starting from the outside or bottom layer are:
