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. IyengarHe who has learnt to control his tongue has attained self-control in a great measure. When such a person speaks he will be heard with respect and attention. His words will be remembered, for they will be good and true. When one who is established in truth prays with a pure heart, then things he really needs come to him when they are really needed: he does not have to run after them. The man firmly established in truth gets the fruit of his actions without apparently doing anything. God, the source of all truth, supplies his needs and looks after his welfare.
B.K.S. IyengarThat's the beauty of backbends. Emotionally we can never be disturbed, for the emotional centre becomes an extrovert. When you do Viparita Dandasana, your head looks backwards, but your conscious mind stretches everywhere. Study by observing how the mind gets regulated. You not only know the freedom in the spine, but also the freedom in the spirit.
B.K.S. Iyengar
