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. Bhaktisiddhanta launched a missionary effort in the 1930s to London that involved members of the British cabinet. The lecture will also present some of the latest research on Bhaktisiddhanta featuring the recent discovery of his diary and an autobiographical sketch. The lecture is based on Sardella’s monograph titled “Modern Hindu Personalism: The Life, Place and Works of Bhaktisiddhanta Sarasvati” to be published by Oxford University Press. Dr. Ferdinando Sardella is based at the Department of Theology, Uppsala University (Sweden) and is a Research Fellow at the Oxford Centre for Hindu Studies.
