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.
Take up one idea. Make that one idea your life -- think of it, dream of it, live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success, and this is the way great spiritual giants are produced. Others are mere talking machines.
-Swami Vivekananda
