In between finishing a commission for a client in Wisconsin, I took a few photos to show the process of creation of a yantra. They look beautiful and simple when done, as they are geometric.

It is actually time consuming and takes a lot of concentration and patience. So here are a few images that show some the final yantra and a few of the steps just of drawing.
