A simple technique for purifying the frontal portion of the brain. In Sanskrit, Kapal means 'skull' and Bhati means 'to shine to clean.' For kapal bhati, exhale slowly through nostrils and simultaneously pull your stomach inwards, that is contract the abdominal muscles to expel air from your lungs. Let the abdominal muscles move inwards to the maximum degree and on inhaling deeply set the abdominal muscle move out wards to the maximum degree.
Sit comfortably in padmasana, with the spine, neck, and head erect. Rest your heads in gyan mudra on the respective knees and be relaxed. Exhale through the nostrils and contract the middle and lower portion of the abdomen. Release the contraction of theabdomen muscles quickly and follow at once with another expulsion of breath freely. Increase the frequency, firmly to 80/20 strokes per minute.The chest and shoulder should be kept immobile during the entire practice. Exhalation should be vigorous and accompanied by the contraction of abdomen, while inhalation should be effortless and passive. Neither there should be any pant between two strokes nor any retention of breath. The exhalation should be done in force and rapidly and the rhythm should be maintained.
Kapal bhati cleans the respiratory tract including the nasal passages and capillaries of the remotest part of the body. It helps in elimination of gases from the stomach, intestines and purifies the renal portion of the grain. It helps in chronic bronchitis, asthma, cerehol thrombosis, diabetes and nervous disorders.
