Speaking, Yantra means "machine" or "contraption". Prime among the Yantras is the Sri Yantra, a 12,000-year-old mystical symbol which is considered the "mother of all Yantras". What is that, you ask? Well, part of the mathematical allure is the fact that you see it all around you in nature, and that is nowhere as true as in the case of the magical number: 1.1618, better known as the Golden Proportion. Every natural pattern is composed regarding this ratio.
![The Shri Yantra, Sri Yantra, or Shri Chakra is a form of mystical diagram (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.[1] When the two-dimensional Shri Yantra is represented in three dimensions, it is called a Mahameru.
