In Narayaneeyam, a poetical hymn of 1036 verses, Narayana Bhattatiri (16th century) gives a masterly summary of the subject matter dealt with in the 14,000 verses of the Bhagavata Purana. A close study of this work will help one gain an insight into authentic Bhakti traditions of India in a short compass. Besides this, the book is noted for the fascinating way in which it portrays the life and achievements of Sri Krishna
Discriminate within yourself between the real and the unreal. Have you not read the Vedanta? Even when you sleep, keep the sword of discrimination at the head of your bed, so that covetousness cannot approach you even in dream. Practicing such strength, renunciation will gradually come, and then you will see the portals of heaven are wide open to you.
-Swami Vivekananda
