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.
The animal has its happiness in the senses, the human beings in their intellect, and the gods in spiritual contemplation. It is only to the soul that has attained to this contemplative state that the world really becomes beautiful.
-Swami Vivekananda
