Breathing is the essence of yoga
During your practice breathe naturally, without forcing.
No pressure, no disturbance, nothing should interfere with the simple, tide-like movement of our lungs as we breath in and out.
Whether you are doing asanas, pranayama (breath control) or meditation, find your breath and take your breath deep into the different layers of your being. Allow yourself to consciously experience your whole breathing cycle
