Monkey cannot be a god. But if I would like to believe that God is in that form, then there is no harm, because God is Omnipresent. Per Hindu beliefs, God is omni present and omni potent. He is present in every form, and can you show a place where God is not present?
If God is present everywhere, then why not in a Monkey ??? If you do not agree with it, then it is fine, I agree that there is no true shape to God and that is the beauty of Hinduism. Hence I stated that Islam and other religions will need another 3 to 4 milleniums to achieve the spirutuality of hindu thought.
