Bhaktisiddhanta Sarasvati Thakura (1874–1937) appeared in Jagannatha Puri as Bimala Prasad Datta, the son of Bhaktivinoda Thakura. Young Bimala Prasad was intellectually precocious and later became known as a living encyclopedia. After initiation by Gaurakishora Dasa Babaji, he was known as Varshabhanavi-dayita Dasa. Bhaktisiddhanta Sarasvati Thakura was his sannyasa name. He was fearless and unyielding in debate, and became known as the “lion-guru.” He was also a revolutionary preacher: rather than renounce the latest technology, he used it to attract people to Krishna consciousness. He published many books and periodicals and various writings of the previous Vaishnava acharyas. He excavated Lord Chaitanya’s birthsite in Mayapur and built a temple there. He established sixty-four temples, and he initiated many disciples, the most prominent being His Divine Grace A. C. Bhaktivedanta Swami Prabhupada.
