Query: The Most Complete Biography

Swami Saradananda's extensive biography is essential reading for anyone who is truly interested in the extraordinary life of Sri Ramakrishna. While not recommended as an introductory text (Christopher Isherwood's "Ramakrishna and His Disciples" would be more suitable), this two volume biography is the most complete and comprehensive work ever written about the Great Master by one of his foremost disciples. It historically illustrates many of the extraordinary and mundane details of the Master's life. A must-read for true devotees.
