Bhakti Ratnavali - or A Necklace of Devotional Gems
Compiled by Vishnu Puri
An anthology of about four hundred verses selected by a medieval ascetic named Vishnu Puri, from the Srimad Bhagavata. In these verses we get a clear outline of the doctrine of Bhakti, both in its theory and practice, as conceived by the great devotional text, the Bhagavata.
Learning and wisdom are superfluities, the surface glitter merely, but it is the heart that is the seat of all power. It is not in the brain but in the heart that the Atman, possessed of knowledge, power, and activity, has its seat.
-Swami Vivekananda
