Sri Madhvacarya: His Life, Religion and Philosophy
Swami Tapasyananda
Madhvacharya points out how Bhakti is both a means and an end in itself. Knowledge generates love and love strengthens knowledge. Madhvacharya is a very fine logician and holds the doctrine of the five types of difference or Bheda.
If a piece of burning charcoal be placed on a man's head, see how he struggles to throw it off. Similar will be the struggle for freedom of those who really understand that they are slaves of nature.
-Swami Vivekananda
