Willpower is concrete, not ethereal. When you do something, you demonstrate your willpower, and it becomes all the easier to have the same power of will the next time.
B.K.S. IyengarIt is through the body that everything comes to the mind. It is through and with your body that you have to reach realization of being a spark of divinity. How can we neglect the temple of the spirit?
