Raja Yoga the Yoga of Meditation : The Pathway to Transformation

Yoga falls into four categories. The first, being the yoga of devotion, is termed ?bhakti yoga.? The second, being yoga of service, is termed ?karma-yoga.? The third, being yoga of wisdom, is termed ?jnana-yoga.? And the fourth, being yoga of meditation, is termed ?raja-yoga.? There are, of course, other forms of yoga that are accessories to the four main categories. What we are concerned with here is raja-yoga.
