We offer many great books for spiritual aspirants. Books such as The Gospel of Sri Ramakrishna, Complete Works of Swami Vivekananda, Gospel of the Holy Mother, etc. are all great reading. Much as we admire them and find them so helpful, it really helps to have a living exemplar, a radiant presence before us so that the teachings become vibrantly alive.
Sad to say, not everyone is blessed to have a person of realization to serve as a model. But all is not lost. We have a number of books you can read that are like being in the presence of these great souls. Many of the books are unfortunately not popular books. Consider For Seekers of God. Reading the book is like being with Swami Shivananda, one of the original disciples of Sri Ramakrishna. In the book, we are up late at night with him as he talks about spiritual matters. In the "As We knew Him" series, the writers take you into the presence of the illumined soul as they describe incidents with them that changed their lives.
