Clearing and releasing.
Clearing and releasing excess energy is extremely important. It is important to do before and after magical working so your energy will flow freely and will not cause you difficulty.
Some of the signs of excess energy are dizziness, lack of balance, feeling giddy, disorientation, hyper-activity, and/or the inability to sleep after a magical working.
Get into a comfy position. It doesnt matter if you are sitting, kneeling, or lying down, but NOT STANDING, as you may not be able to keep your balance until you are proficient in the technique.
Visualize a bright white light pouring down from above: the top of your head, passing through your whole body, and exiting through the soles of your feet. Release all tensions, anxieties, and stresses. Imagine them flowing out of you along with the light. Let it all pour out over you. Imagine the excess energy as little bits of darkness being carried away with the light as it flows through you. When the last bits of darkness are gone, let the light stop coming down and let the last of it to flow through you.
Note: you can substitute water for the light.
In any case the excess energy returns to the Goddess, to be recycled for use elsewhere. You may say an affirmation when you are releasing like I clear and release all excess energy or I release this energy to the Goddess to be used elsewhere
This method was taught to me by my mentor many moons ago. There are many ways to do this, but this is the one that works best for me.
