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. IyengarWhen the restlessness of the mind, intellect and self is stilled through the practice of Yoga, the yogi by the grace of the Spirit within himself finds fulfillment.
B.K.S. IyengarDo not allow past experiences to be imprinted on your mind. Perform asanas each time with a fresh mind and with a fresh approach. If you are repeating what you did before, you are living in the memory, so you are living in the past. That means you don't want to proceed beyond the experience of the past. Retaining that memory is saying, 'Yesterday I did it like that.' When I ask, 'Is there anything new from what I did yesterday?' then there is progress. Am I going forward or am I going backward? Then you understand how to create dynamism in a static asana.
