The word yoga comes from the root yuj, meaning to align. Fear destroys teh alingment of the mind; rather than accept the reality of nature, the mind seeks to change and control it. These attempts invariably fail, creating frustration and fear and confusion that blinds ones to spiritual reality. Yoga restores mental alignment so that nature is seen for what it is. : Devdutt Pattanaik, 7 Secrets of Shiva.
