Some short exercises:
As you breathe in, draw fresh energy in through the base of spine. Allow the energy to transmute as it rises up the spine. Be aware of the light when you get to the top of the spine. As you breathe out allow this light to wash down through your body releasing pollution, feeling it eliminate, flowing down and out of the body.
Breathe magnetism into the body. Hold your breath a comfortable amount of time, and feel the magnetism charge the cells, the organs, the systems, etc, making them vibrate with new energy and magnetism. Breathe out and feel old pollution leave as you are re-energized.
Breathe in light to the cells of your body. Include the skin, organs, systems (circulatory, digestive, hormonal etc), the connective tissue - everything. Hold your breath a comfortable amount of time, feeling light sparkle in the body - in the cells. Breath out and let yourself transform.
