Yoga is the control of thought waves in the mind
According to Patanjali, the mind is made up of three components, Manas, Buddhi and Ahankaara. Manas records the impressions gathered by senses. Buddhi classifies these impressions and reacts accordingly. Ahamkaara is the ego sense which claims these impressions for its own.
