Gyan Marg and Gyan Yog Compared
Gyan Marg and Gyan Yog are closely related but not identical. Gyan Marg culminates in Atma-Gyan, while Gyan Yog continues through Bhakti and Divine Grace to Brahm-Gyan and liberation from Maya.
The terms Gyan Marg and Gyan Yog are often used interchangeably. However, the scriptures make an important distinction between them.
Gyan Marg refers to the path of spiritual progress that leads a qualified seeker toward Atma-Gyan, the realization that he is the eternal soul distinct from the body and mind.
Gyan Yog refers to the continuation of Gyan Marg after Atma-Gyan, where the seeker performs Bhakti of the Personal Form of God and, through Divine Grace, attains Brahm-Gyan.
Thus, Gyan Yog is not separate from Gyan Marg. Rather, it is the culmination of Gyan Marg through Bhakti.
