Pranayama may be broadly divided into two categories:
(a) When there is no digital control over the nostrils.
(b) When the thumb and two fingers of the right hand are used to regulate and control the flow of breath through the nose. This is called digitally controlled pranayama. Moreover, this pranayama is of two types:
(i) Inhalation and exhalation arc practised on both sides of the nostrils, partially closing them to learn to use pressure and balance on the thumb and fingers for an even flow of breath from both nostrils.
(ii) Wherein one nostril is kept blocked with the fingertips, while the breath is made to flow from the thumb side and vice versa. For example, if the breath is drawn from the right side, the ring and little fingers should be made to close the left nostril without disturbing the position of the septum and vice versa. Care is taken that the breath should not flow in the blocked nostril’.Iyengar BKS, Light on Pranayama p.159
