Anuloma pranayama is a practice to sensitize your nostrils to the flow of the breath so that you can actually follow the breath to the center of the mind. This practice consists of a powerful exhalation and a relaxed inhalation through the same nostril all the way to the center of the mind, through each nostril three times. It works on clearing the channels in order to allow your focus to be at your center, ultimately resting your awareness in the pranic field that you have created in the mind.
