Know your capacities and continually improve upon them.

Asanas keep your body, as well as your mind, healthy and active

There must be relaxation in full extension.

It is not yoga that injures, but the way one does yoga that leads to injury.

Yoga uses the body to discipline the mind and to reach the soul.

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.

The practice of yogasana for the sake of health, to keep fit, or to maintain flexibility is the external practice of yoga. While this is a legitimate place to begin, it is not the end. Even in simple asanas, one is experiencing the three levels of quest: the external quest, which brings firmness of the body; the internal quest, which brings steadiness of intelligence; and the innermost quest, which brings benevolence of spirit.
