What is "saradananda"

Saradananda (23 December 1865 – 19 August 1927), also known as Swami Saradananda, was born as Sarat Chandra Chakravarty in 1865, and was one of the direct monastic disciples of Ramakrishna. He was the first Secretary of the Ramakrishna Math and Ramakrishna Mission, a post which he held until his death in 1927. He established the Udbodhan house in the Bagbazar area of Calcutta, which was built primarily for the stay of Sri Sarada Devi in Calcutta, from where he used to publish the Bengali magazine Udbodhan. There he wrote Sri Sri Ramakrishna Lilaprasanga in Bengali, on the life of Ramakrishna, which was translated into English as Sri Ramakrishna, the Great Master.
