The purpose of Yoga is to facilitate the profound inner relaxation that accompanies fearlessness. The release from fear is what finally precipitates the full flowering of love.
Your body's ability to function as a clean and efficient channel is limited by stiffness, lack of strength, and lack of endurance. Your mind's ability is limited by the way it thinks about itself, by the way you think about you. The process of yoga is one of undoing the obstructions and limitations in your body and mind that inhibit the free flow of creative life force.
Stillness is not the absence or negation of energy, life, or movement. Stillness is dynamic. It is unconflicted movement, life in harmony with itself, skill in action. It can be experienced whenever there is total, uninhibited, unconflicted participation in the moment you are in—when you are wholeheartedly present with whatever you are doing.
Yoga is a way of moving into stillness in order to experience the truth of who you are. The practice of yoga is the practice of meditation-or inner listening-in the poses and meditations, as well as all day long. It's a matter of listening inwardly for guidance all the time, and then daring enough and trusting enough to do as you are prompted to do.
