This book incorporates some of the practical lectures on devotion delivered by Swami Vivekananda. Here he discusses the preparatory disciplines, the importance of the guru and how to choose one, the principles of ritual worship, the chosen ideal, and finally, the supreme love. This book differs from the Swami's Bhakti Yoga lectures, not in subject matter, but in his treatment of the subject here in an intensive, yet more easily appreciable form.
Think day and night, I am of the essence of that Supreme Existence, Knowledge, Bliss--what fear and anxiety have I? This body, mind, and intellect are all transient, and That which is beyond these is myself.
-Swami Vivekananda
