“Fusing Fire and Water This is a moving exercise in which the hands help raise and lower chee between the Sea of Energy (water) and the heart (fire). Posture: Horse stance, or sitting Technique: Exhale thoroughly and bring your hands together just below the navel, with palms up and fingertips about an inch apart. Begin inhaling slowly through the nose and slowly raise your upturned hands the torso until they reach the nipples. Time it so that inhalation is complete and hands reach the heart about the same time. Apply the Three Locks and retain the breath 3 to 5 seconds, then turn the palms over to face downward and slowly push them back down the torso as you exhale slowly through the nose, timing it so that hands reach bottom as lungs empty. Pause briefly, relax abdomen, then turn the palms back up and begin another cycle. Repeat 6 to 10 breaths. Pointers: Breathe and move hands in unison. Keep shoulders, arms, and neck muscles loose and relaxed, and “sink” the breath down as deeply as possible during retention. Benefits: This exercise moves energy up and down between the “fire” of heart and the “water” of the navel region, thus blending and balancing these two types of energy. It regulates and deepens heartbeat and develops awareness of the Sea of Energy as the body’s chee headquarters.”
