Gadadhar Chattopadhyay is the original name of Ramakrishna Paramahamsa. He was an Indian mystic and yogi during the 19th-century. He was given to spiritual ecstacies from a young age, and was influenced by several religious traditions, including devotion toward the goddess Kali, Tantra, Vaishnava bhakti, and Advaita Vedanta. Admiration for him amongst Bengali elites led to the formation of the Ramakrishna Mission by his chief disciple Swami Vivekananda.
