“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.”
