The Yoga-Darshana includes the Yoga-sutras of Pantanjali and the ancient commentary thereon by Vyasa. The Yoga-sutras of Pantanjali are the classic formulation of the science of meditation. This science is called raja-yoga, the kingly yoga. Because through it one learns to rule one's own mind. Human psychology is analyzed from this standpoint and the resulting system of meditation is delineated, all in 195 terse sutras (threads of thought).
