The Sri Yantra also called Sri Chakra is a beautiful and complex sacred geometry used for worship, devotion and meditation. It has been in use for thousands of years and it's origin seems unknown. The central figure is composed of nine interlocking triangles. Every triangle is connected to the others by common points and this is the reason why it is so difficult to draw correctly. Changing the size or position of one triangle often require changing the position of many other triangles. After making a few attempts at drawing this figure it becomes obvious that it's not as easy as it looks. Given the fact that this is one of the oldest and most recognizable sacred geometry one would assume that a method for drawing this famous figure precisely would be easy to find. Not so. The two most famous methods from Indian origin, shown here and here are very imprecise and/or incomplete. After looking carefully at the figures produced by these different techniques one realizes that they are all different! Was there an original geometry that has been lost with time? Is there a way to find out? These are some of the questions that are answered here.
The optimal Sri Yantra is the configuration that we consider to be the closest to the original figure after doing an in depth mathematical investigation. See the article here for more information. An optimal Sri Yantra must satisfy all of these three caracteristics:
1. Concurrency:   All triple nodes meet at one point. 2. Concentricity:  The center of the innermost triangle and the enclosing circle coincide. 3. Equilaterality:  The innermost triangle is equilateral. Read the article here: Solving the Sri Yantra

### Plane

The most common form of the Sri Yantra. The inner nine triangles are drawn with straight lines and are contained in circles and squares drawn on a flat plane.

### Pyramidal (Meru)

This is basically a 3D version of the plane form. The outline formed by the overlapping triangles are elevated in steps to form a pyramid.

### Spherical (Kurma)

This is the rarest and the most difficult to reproduce. The figure is drawn or sculpted on a dome shape. The triangles are drawn with curved lines (spherical triangles) making it very difficult to achieve a precise result.

### Temples and Carvings

Pictures of temples in the shape of the Sri Yantra and pictures of Sri Yantra carvings.
