Many ask me whether pranayama ... postpones old age. Why worry about it? Death is certain. Let it come when it comes. Just keep working. The soul has no age. It doesn't die. Only the body decays. And yet, we must never forget the body, since it is the garden we must cherish and cultivate.
B.K.S. IyengarPractice doing yoga with an innocent mind. Then, you will be able to cognize the things happening in your body
B.K.S. IyengarYou must fill every inch of your body with the asana from your chest and arms and legs to the tips of your fingers and toes so that the asana radiates from the core of your body and fills the entire diameter and circumference of your limbs. You must feel your intelligence, your awareness, and your consciousness in every inch of your body.
