Just one breath- BKS Iyengar
In Hatha Yoga Pradipika they say that the mind is the king of the senses and the breath is the king of the mind. And if the nerves, nervous system which is about 6,000 miles in our system has a rhythmic vibration then that rhythmic vibration of the nerves becomes the king of the breath. I will show you the inhalation and exhalation to experience the rhythm of the sound of breath...
That is inhalation. Did you experience the beauty of that sound?
So also exhalation...
