The law of Yoga is the law of Life. Yoga embodies the secrets of successful living and combines profound and age-old truths with a way of life acceptable to the modern mind. The basic principle of purification underlines all Yogic practices and at the same time it aims at establishing a balance in the body so that it functions, as it were, like a perfect machine. When this state of physical balance is achieved the mind can then be controlled and can realize the ultimate in pure thought and reason.
