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.

B.K.S. IyengarYou have to get rid of borders, limits, and classifications; then light comes. We see everything on the screen of our ideas. We must get rid of that screen to be able to see what is behind. X's ideas are limited, that is why he remains on the surface. Y got rid of the limits, so she always goes to the depths. We should always meet people and new subjects with no set frame of mind. We have to live like that even after long acquaintance. We must get rid of every set idea to approach everything and everyone with love.
B.K.S. IyengarYou must do the asana with your soul. How can you do an asana with your soul? We can only do it with the organ of the body that is closest to the soul - the heart. So a virtuous asana is done from the heart and not from the head. Then you are not just doing it, but you are in it. Many people try to think their way into an asana, but you must instead feel your way into it through love and devotion
