Bhaktisiddhanta Sarasvati Thakura was the spiritual master of His Divine Grace A.C. Bhaktivedanta Swami Prabhupada, the Founder-Acharya of ISKCON. Srila Bhaktisiddhanta Saraswati Thakura powerfully spread the teachings of Chaitanya Mahaprabhu in the early twentieth century. He preached strongly against the deep-rooted influences of caste-ism and impersonalism. Meeting with scholars, educators, and other leaders and writing over 108 essays and books, he strove to present Krishna consciousness as a science to be highly esteemed. He established 64 temples, known as Gaudiya Maths, inside and outside of India.
He asked his disciple A. C. Bhaktivedanta Swami Prabhupada to go to the West to teach Krishna consciousness. Srila Prabhupada went to New York in 1965 and carried on his spiritual master’s mission on a grand scale.
