When you can “hear” your blood pressure or feel your heart pumping fast, take a deep breath and sink into yourself. Take another breath and sink some more. With each breath, feel yourself sink as much as possible. When you have sunk as much as possible, visualize your energy spreading out. You may notice that the energy in your heart is thick. Visualize sticking a straw into it and siphoning out the thick gunky energy. Siphon it into a bubble of light and send it away. See it dissolve into the light.
Then put all your attention on your heart. See it in a deflated sack. Visualize blowing Love into the sack until your heart is saturated in Light and is free-standing in a clear strong globe of Light. Hear the Bee Gees song Saying Alive playing in the background and calm the heart down so it is beating in rhythm with the song. If you want to be silly, (humor is relaxing) see your heart dancing on a disco dance floor with a strobe light. See the whole heart sack (pericardium) Filled up with incredible Light.
Visualize the purity and the magnitude of that Light flow through the valves leading out of the heart and into the body. Visualize it being so strong and pure that it dissolves all the stagnant energy that is in the arteries until they are all clear passages. See the purity continue all the way to the veins and clean out the veins as well. Sense the energy loop around the body in a fluid, cohesive, calm rhythm. Feel the Love literally coursing through your veins.
Visualize changing your vantage point so that you see your body as the globe of light with the loops of Lights coming and going from it and seeing it as a pure flowing structure. Practice doing this technique many times until you can conjure it up in moments and give good energy to your heart and whole cardiovascular system at will.
