Yoga is a science of Holistic living and not merely a set of Asanas and Pranayama. It is a psycho physical and spiritual science, which aims at the harmonious development of the human body, mind and soul. Yoga is the conscious art of self-discovery. It is a process by which animal man ascends through the stages from normal man to super man and then the divine man. It is an expansion of the narrow constricted egoistic personality to an all-pervasive eternal and blissful state of reality. Yoga is an all round development of personality at physical, mental intellectual, emotional and spiritual level.
