It was Pathanjali Maharshi who first advocated yoga as a science. In his book 'Pathanjala Yogasoothram', he has brought to light the tremendous power of yoga.
The practice of yoga opens the way to a happy and harmonious life. Self- confidence, maturity, intelligence and sharp memory are the qualities, a regular yoga practitioner is endowed with. In other words, by enabling you to uncover the latent abilities of your mind and body, yoga turns you into a wholesome personality.
