Chakra Hand Postures -- these mudras and bijas (seed sounds) have real physiological basis--they help us to propriocept in our physical bodies where there are restrictions or blockages that prevent prana (life force) from flowing freely into and throughout the body and can actually remove these restrictions.
Lightly hold each finger one at a time. Begin with your right thumb, exhale and inhale 36 breaths (or 3-5 minutes). Continue with each finger. Do the right hand, then the left. If you don’t have time for both hands, hold the side that feels most tense.
