The Shri Yantra or Shri Chakra is a form of mystical yantra used in the Shri Vidya school of Hinduism. 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, Shri Yantra is also known as the Navayoni Chakra. When the two-dimensional Shri Yantra is represented in three dimensions, it is called a Mahameru. name from this shape. It is a complex sacred geometry used for worship, devotion and meditation. Yantra means 'instrument' or 'machine' in Sanskrit. This sacred symbol is in use for thousands of years, and its origin is clouded in mystery.
