We all are servants of servants of servants of Srilla Bhaktivinoda Thakura and all our knowledge and understanding is uprising from his teachings and books. We are members of the glorious transcendental family of Srilla Bhaktivinoda Thakura, Bhaktivinoda parivara and therefore, we take his words as supreme guidance and shelter.
Here is interesting text written about Srilla Bhaktivinoda Thakura and Gaura Kaisora das Babaji by Srila BR Sridhara Deva Gosvami Maharaja in his book Follow the Angels:"Now, suddenly, these two personalities have come to the surface, Gadadhara Pandita and Svarupa Damodara. Both have come. Svarupa Damodara came as Gaura-kisora and Gadadhara Pandita came as Bhaktivinoda Thakura".
"The position of Bhaktivinoda Thakura is so exulted that at the end of his commentary on Caitanya-caritamrta, Srila Bhaktisiddhanta wrote that he saw Bhaktivinoda as Gadadhara Pandita".
