His Divine Grace Gaudiya Gosthipati Srila Bhakti Siddhanta Sarasvati Goswami Prabhupad
It is better not to talk about people belonging to useless, unauthorized sampradyas. You should continue chanting the Holy names of Hari without offense, avoid bad association, and read Sri Chaitanya – caritamrita, Prarthana, Kalyan Kalpataru, and Prema-bhakti-candrika. This will certainly benefit you.
Blasphemy of others should be rejected.
