Yoga is one of the six systems of Indian philosophy. The word yoga originates from the sanskrit root yuj which means Union. On the spiritual plane, it means union of the Individual Self with the Universal Self. Yoga is the union of the body, mind, emotions and intellect. Sage Patanjali penned down this subject in his treatise known as Yoga Sutras of Patanjali.
