Mahapurush Swami Shivananda, one of the direct disciples of Sri Ramakrishna and the second President of the Ramakrishna Order, was a person who had scaled the depths of the Divine. His letters to devotees and spiritual seekers were treasured by them as unfailing blessings for the rest of their life. This book is a collection of the more important of these letters.
The book one must read to learn natural sciences is the book of nature. The book from which to learn religion is your own mind and heart.
-Swami Vivekananda
