Hold the fingers of the right hand in front of the face. Rest the index and middle fingers gently on the eyebrow centre. Both fingers should be relaxed. The thumb is above the right nostril and the ring finger above the left. These two digits control the flow of breath in the nostrils by alternately pressing on one nostril, blocking the flow of breath, and then the other. The little finger is comfortably folded. When practising for long periods, the elbow may be supported in the palm of the left hand, although care is needed to prevent chest restriction.
