This year marks the 75th anniversary of Bhaktisiddhanta Sarasvati's (1874–1937) passing away. Bhaktisiddhanta Sarasvati was the founder of the Gaudiya Math and the inspirator of a wide range of Vaishnava movements that have been established in the West from the 1930s and onwards, among others ISKCON or the Hare Krishna Movement. The lecture discusses the relationship of Bhaktisiddhanta with modernity, his theological ideas in relation to Christianity, and his approach to Western culture.
