The Rig Veda defines yoga as a union or "yoking" of the material and spiritual worlds, and it doesn't describe any physical postures other than the traditional cross-legged meditation pose.
Deepak ChopraNever forget that you are not in the world; the world is in you. When anything happens to you, take the experience inward. Creation is set up to bring you constant hints and clues about your role as co-creator. Your soul is metabolizing experience as surely as your body is metabolizing food
Deepak Chopra
