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.
I am the thread that runs through all these pearls, and each pearl is a religion or even a sect thereof. Such are the different pearls, and God is the thread that runs through all of them; most people, however, are entirely unconscious of it.
-Swami Vivekananda
