Srila Prabhupada Bhakti Siddhanta Sarasvati Gosvami Thakur used to say that—“ Siddhanta vicar is not a matter of practice like Gymnastic fits, so that anybody can speak and write perfect Siddhanta without doing perfect Sad Guru seva. This can never be like a mentally concocted thought. Srila Bhaktivinod Thakur used to speak that—“ One sadhu ( a genuine pure sadhu ) from northpole, and another sadhu from southpole, both of them can speak the same siddhanta on any Siddhanta vicar relating to aprakrita seva, maybe the way of representation and language different. Aprakrita Siddhanta vicar coming down from that Vaikuntha Jagat and appear inside the heart of a genuine sat Guru sevaka.
