At the root of all psychic development is good breathing. There is a life-giving property from fresh air, and the fact that simply by breathing fully you contribute to living fully.
Breathing Exercise:
1. Stand before an open window, or out of doors, free from all restrictive clothing. Exhale forcibly, bending the body forward and relaxing the muscles. Then stand up straight and place both hands over the abdomen. Now breathe as deeply as possible against those hands, expanding the abdomen as much as possible without allowing the chest or ribs to expand at all. Again, exhale forcibly.
2. After five or six such breaths, place your hands on either side of your ribs. Now breathe in deeply, pressing out the ribs but without allowing either the abdomen or the upper chest to expand more than a little.
3. After five or six breaths, place your hands on your upper chest, just below the neck, and breathe with this portion of the lungs, without allowing either the ribs or the abdomen to expand.
4. You will find that it is not so easy to control your breathing. After you have mastered it however, you can go on to the next step, the complete breath:
5. Take a number of good, deep breaths, starting with expanding the abdomen, then the ribs, then the upper chest, one after the other in the one breath. Try to control this intake in the three stages, one after the other. Then, as you become more accomplished, merge them one into the next, so that you have something akin to a rolling motion as the breath moves up the body. Breathe in through the nose and out through either the nose or mouth.
From there, continue with establishing a mental image of the breath as you breathe it, in the form of light.See it coming into the body and filling it. As you breathe out, see the breath and the light forcing out all the negativity in dark colors: black, dark browns, green and red. You can imagine the light entering in from wherever it feels most comfortable to you - through the third eye, into the heart, up from the ground through the feet, from above down to the crown, whichever you prefer. Just be consistent and always see it entering in the same place.
For the exit of the negativity, see it being driven out of all the bodily orifices, one after the other, and end with it leaving all the pores of the skin. End with the whole body, every little extremity, completely filled with fresh, vibrant, positive light.
