This exceptional book is a compilation of five different essays which Srila Gurudeva has written over the past 20 years in defense of Gaudiya sampradaya tattva siddhanta. Each refutation is elaborately and conclusively proven with evidence from sastra.

Included in this edition are two lectures by Srila Gurudeva which glorify and follow the example of Srila Bhaktisiddhanta Sarasvati Gosvami Prabhupada who boldly re-established the true conceptions of Sriman Mahaprabhu and the gosvamis, and began the preaching mission which is today bringing this pure bhakti tattva siddhanta to every country in the world.
