Sit somewhere on the ground outside. Close your eyes, and relax. Imagine white roots going from your body and into the earth. Picture them going down, and down. After a few minutes, visualize them entering the center of the earth. Imagine a large white ball of golden and white light. Let you roots surge forward and jump into the energy. Pictures the roots filling with gold and white light. Imagine the energy going up your roots fast. After a few minutes, the light reaches you and fills you with energy. Continue to draw the energy from the earth. Once you think it's enough, take the roots out of the light and picture them coming back up through the earth. After a few minutes, they should have reached you and gone back into your body. Breath in and out. Visualize the energy spreading through your body. When you're ready, open your eyes.
