The Indian philosophical system of yoga promotes a conscious way of life that expands perception beyond materialism and duality. Yoga leads us to free ourselves from unwanted habits, to become aware of self-limiting programming imprinted in the mental machine, to transcend the mechanization of behavior, and to cultivate harmony and simplicity. Aligned physical posture, conscious breathing, focus of the rays of the mind, formation of levels of existence, unified consciousness declare the effective application of yoga.
