Yoga and Pranayama have their origin in India and have taken a form of Science, which is considered to be a great legacy of India to the world. Though its origin is shrouded in antiquity, it was organised in a definite system by Maharshi Patanjali in his treatise "Yoga Darshana" (Philosophy of Yoga) or "Yoga Sutra" (Aphorisms on Yoga) as it is popularly known. Every science develops its own terminology. So is the case with the science of Yoga.
