The material layers of the individual are the body, mind and intellect. These need to be used diligently to unravel the Supreme Self within. The three yogas are Karma (Action) for the body, Bhakti (Devotion) for the mind, and Jnana (Knowledge) for the intellect. These disciplines need to be carefully understood. Then practised in the right proportion to ensure comprehensive development of the personality.
