“Without certain stress, the true asana is not experienced, and the mind will remain in its limitations and will not move beyond its existing frontiers. This limited state of mind can be described as the petty, small mind.”
― B.K.S. Iyengar, Light on Life: The Yoga Journey to Wholeness, Inner Peace, and Ultimate Freedom

“As mammals, we are homeostatic. That means we maintain certain constant balances within our bodies, temperature for example, by adapting to change and challenge in the environment. Strength and flexibility allow us to keep an inner balance, but man is trying more and more to dominate the environment rather than control himself. Central heating, air conditioning, cars that we take out to drive three hundred yards, towns that stay lit up all night, and food imported from around the world out of season are all examples of how we try to circumvent our duty to adapt to nature and instead force nature to adapt to us. In the process, we become both weak and brittle. Even many of my Indian students who all now sit on chairs in their homes are becoming too stiff to sit in lotus position easily.”

“When you stand in the warrior pose with your arms extended, you can see the fingers of your hand in front of you, but you can also feel them. You can sense their position and their extension right to the tips of your fingers. You can also sense the placement of your back leg and tell whether it is straight or not without looking back or in a mirror. You must observe and correct the body position (adjusting it from both sides) with the help of the trillions of eyes that you have in the form of cells. This is how you begin to bring awareness to your body and fuse the intelligence of brain and brawn. This intelligence should exist everywhere in your body and throughout the asana. The moment you lose the feeling in the skin, the asana becomes dull, and the flow or current of the intelligence is lost.”

“When we direct our eyes looking forward from the corner of the temple in its normal field of vision, the frontal brain is working with analysis (vitarka). But when we spread our ocular awareness from the back corner of the temple, near the ear, the back brain is brought into play and works with synthesis (vicara). The front brain can dismantle because of its powerful penetration. The back brain is holistic and reassembles. If you find this difficult to imagine, just think what happens when you first walk into a great medieval cathedral. Your eyes may appear to focus on what is before them, the altar for example, but your real awareness takes in the whole immense volume of the space surrounding you, its grandeur and the hum of its ancient silence. This is holistic meditative vision. While working in asana, if the action is “done” solely from the front brain, it blocks the reflective action of the back brain. The form of each asana needs to be reflected to the wisdom body (vijnanamaya kosa) for readjustment and realignment. Whenever asana is done mechanically from the front brain, the action is felt only on the peripheral body, and there is no inner sensation, there is no luminous inner light. If the asana is done with continual reference to the back of the brain, there is a reaction to each action, and there is sensitivity. Then life is not only dynamic, but it is also electrified with life force.”
