Sri Ramakrishna the Great Master, translated by Swami Jagadananda (a disciple of Sarada Devi),[1] is an English translation of the Bengali biography Sri Ramakrishna Leela Prasanga, of Sri Ramakrishna, the 19th-century Indian saint and mystic. Its Bengali original was written by Swami Saradananda, which is based on interviews of persons who knew or interacted with him. It is therefore a first-hand source. The original Bengali version published was composed in five volumes and was the first full-scale biography of the saint.[2] This is an eyewitness account and therefore carries more credibility than later books on Sri Ramakrishna. The English translation was first published in 1952. The original Bengali book was written from 1909 to 1919, over a period of ten years, in order to repay the debt incurred for constructing Udbodhan House for Holy Mother Sri Sarada Devi.[3]
