Dr. O.B.L. Kapoor classic work on Krishna Bhakti. In this book, expanded from a 1973 Back to Godhead article, Dr. Kapoor explores the meaning of Bhakti through the experiences of great Vaishnava practitioners and saints. He isolates what he considers the four major traits or "laws" of Bhakti, illustrating each of those laws with numerous stories from the lives of the great Bhakti saints, such as Lokanatha Goswami, Sanatana Goswami, Gauranga Dasa Babaji, and many others. This book is great for both those interested in the science of bhakti and those interested in the lives of the great Vaishnava saints..
