Srila Bhakti Siddhanta Saraswati Goswami Thakur Prabhupad, the disciple of Srila Gaura Kisora Das Babaji Maharaj, was the Guru of both Srila Bhakti Rakshak Sridhar Maharaj and Srila A.C. Bhakti Vedanta Swami Prabhupad.
Srila Bhakti Siddhanta Prabhupad preached that the Gaudiya Math stood for the dignity of the entire human race, by teaching wholesale surrender to the Absolute Good. Especially active in the field of publishing transcendental literature, his erudition was profoundly commanding and elaborate. He revolutionized Krishna conscious preaching by giving preference to pure devotional qualifications over lineage, and it was he who set the precedent of Vaishnava Tridanda-Sannyas [the renounced order of devotional life] in accordance with the injunctions of the revealed scriptures.
In a poem describing the descending divine succession of the Brahma Madhva Gaudiya Sampradaya, Srila Bhakti Siddhanta Saraswati Goswami Thakur Prabhupad wrote: Sri Krishna Chaitanya — Radha-Krishna nahe anya, Rupanuga janera jivana. "Lord Sri Chaitanya Mahaprabhu is none other than Sri Sri Radha and Krishna, the life and soul of the true followers of Srila Rupa Goswami."
To exemplify this sublime ideal, Srila Bhakti Siddhanta established sixty-four Gaudiya Maths in India in the 1930's, and all through he embraced the line of worship of Lord Chaitanya as nondifferent from Sri Sri Radha and Krishna.
The deep sense of urgency he felt to propagate the divine teachings of Lord Chaitanya for the benefit of the suffering world of misconception is exemplified in the indomitable conviction of his statement: "If fire burns the whole world, do not waste time trying to put it out. All necessities can be met only by serving Krishna."
