This biography of the Divine Master Sri Sri Babathakur is a memoir of a eye-witness of His divine life. It contains not only the intricate penfortive incidents of His divine life but also vivid descriptions of apparently insignificant sketches of His mundane existence. It is an evidential document of the life of an introspective seeker then known as ‘Mastermosai’, who later became a self-realizer Sri Sri Babathakur. Sreemati Bani Chakraborty got the rare opportunity to see directly His divine game by staying very close to Him. This treatise draws information from her diary. This is the first volume of a two volume series of the life sketch of the Master.
