You 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.
B.K.S. IyengarMany 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. IyengarYour body exists in the past and your mind exists in the future. In yoga, they come together in the present.
B.K.S. IyengarThe yogi cannot be afraid to die, because he has brought life to every cell of his body. We are afraid to die, because we are afraid we have not lived. The yogi has lived.
B.K.S. Iyengar
