A Guide to Spiritual Life - Spiritual Teachings of Swami Brahmananda
Swami Chetanananda
Readers of this book will feel that these teachings have come straight from the heart of Swami Brahmananda, the spiritual son of Sri Ramakrishna. The swami was a spiritual dynamo and he taught with authority.
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
