The Great Invocation is an awakening, activation, and connection visualization created by Michael Sharp. This visualization rapidly and effectively activates your body's energy system and powerfully and intentionally dispels darkness, "spreads light," and facilitates additional activations.
To do the GI, simply meditate on the following animation. To draw the most benefit, put yourself in the picture. Picture yourself as the "enlightening" being in the middle, and picture your own energy and light spreading out from your now activated chakras into the world around you. For best effect, do bookmark this page and do it multiple times a day. Once you have memorized the visualization, it shouldn't take more than twenty seconds or so to run your mind through it.
