Dewi. Kapalabhati. Pumps must come from below the navel. Begin slowly, careful to release each pump fully, and gradually work up to a maximum rate of two pumps per second. (Don’t go faster than this.) The rest of your body should remain relaxed, so that pranic movement can take place. Watch for signs you are doing too many pumps or straining: lightheadedness, breathlessness, headache … pain in the lumbar spine (L1, L2, or L3).
