The Sri Yantra or Sri Chakra is a form of mystical diagram used in the Shri Vidya school of Hindu tantra. It consists of nine interlocking triangles that surround a central point known as a bindu. These triangles represent the cosmos and the human body. Because of its nine triangles, Sri Yantra is also known as the Navayoni Chakra. When the two-dimensional Sri Yantra is represented in three dimensions, it is called a Maha Meru. Mount Meru derives its name from this shape. In addition to Mount Meru, all other yantras derive the Sri Yantra.
The nine main triangles also form 43 smaller triangles, which is said to represent the entire universe or cosmos. Eight lotus petals surround the triangles, while a larger ring of 16 lotus petals surround both. This is finally enclosed in a temple-like square, which contains four doors.
The word ‘yantra’ means ‘instrument’ and this is exactly what this symbol is: an instrument or powerful tool for intense meditation, prayer or concentration to allow one to achieve a higher level of consciousness. The Sri Yantra acts as a focusing point, with an inner and outer doorway that can lead one to commune with different deities through various levels or force centers in the universe.
