Gyan yoga, also known as gyan marga, is the way of gaining true knowledge of the self. It is the art of union with the Divine, through pursuit of spiritual knowledge. A gyan yogi explores some very basic questions of life such as ‘who am I’ and ‘how am I related to the world as a whole’. Wisdom so gained helps him in getting freedom from the cycle of births and deaths.
Apart from gyan yoga, the other two paths prescribed in Bhagavad Gita are karma yoga and bhakti yoga. Though it is not possible to draw a clear-cut demarcation, but broadly speaking karma yoga and bhakti yoga are suitable for the men of action and men of emotion respectively ; and gyan yoga is pursued by the men of contemplation. One can choose the path of his spiritual freedom depending upon his interest, aptitude and inclination.
