The battle of yoga is with the body and with the ego. You must conquer your ego, or small self, so that you can let your soul, your big Self, be victorious.
B.K.S. IyengarYou 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. IyengarDo not allow past experiences to be imprinted on your mind. Perform asana each time with a fresh mind and with a fresh approach.
