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.
Desire, want, is the father of all misery. Desires are bound by the laws of success and failure. Desires must bring misery. The great secret of true success, of true happiness, is this: the person who asks for no return, the perfectly unselfish person, is the most successful.
-Swami Vivekananda
