Here’s a simple exercise you can try.
Draw a figure like the one below with rice flour or some kind of grain. Place a small ghee, or clarified butter, lamp in a plate full of water at the center. Place a flower in the water. You have now created a geometric form, using water, fire, and air. The flower in the water represents the earth. Akash, or ether, is, of course, always present.
Try this simple process every evening. You will find the energy of your room altered in a subtle but powerful way. In this manner, you can uniquely empower your home or office on a daily basis.
