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
Look here -- we shall die! Bear this in mind always, and then the spirit within will wake up. Then meanness will vanish from you, practicality in work will come, you will get new vigor in mind and body, and those who come in contact with you will also feel that they have really got something uplifting from you.
-Swami Vivekananda
