Why is Dvaita known as the Doctrine of Reality ?
Because that is the correct, and preferred name; the doctrine asserts five differences, not just the one referred to above, and its scholars and proponents call it the ‘doctrine of reality’, where the three kinds of entities in the universe (insentient or jada, sentient or chetana, and Vishnu or Iishvara) are all real, and the differences between any two are also real. Hence, ‘tattva’ means real entity, and ‘Tattvavaada’ means ‘doctrine of real entities’. Some have also referred to Tattvavaada as Bheda-vaada (doctrine of difference), and also as Bimba-pratibimba-vaada (doctrine of object and image – to be explained later), etc. These names are not in normal use.
