A technique of breathwork found in yogic disciplines. Traditionally, the index finger of the right hand is placed above the nose between the eyebrows. The practitioner exhales while using either the thumb or middle finger to close one of the nostrils. This is then repeated with the other nostril. This breathing through alternate nostrils, it is claimed, can be very powerful, although some people suggest it should not be practiced unless you are under the observation of a skilled teacher.
