Kapala”- means “skull” and “Bhati”- means “light”. Kapalabhati
is one of the Shatkarmas or cleansing/purifying techniques. Therefore the purpose of this exercise is not deep breathing but cleansing of the frontal passages. So, it should be performed as a preparatory technique before doing other pranayamas. This technique consists of short, powerful exhales and passive inhales. This exercise is a traditional internal purification practice, or kriya, that tones and cleanses the respiratory system by encouraging the release of toxins and waste matter.
