Many of us often make the mistake of jumping to conclude identity, based on similarity between two things. If two things are similar, that does not mean that they are identical. A cow has 4 legs and so also a dog. That does not make cow and dog same!
The Vijnyaana Vadi Buddhists see the similarity between the dream world and our wakeful world and jump to the conclusion that since dream world is nonexistent, our wakeful world also does not exist! The brahma supporters reject this reasoning. Let us see how.
