The question is are we made in God’s image or is God made in our image? I still subscribe to the theory that this material world is a perverted reflection of the spiritual world and the things that exist here also exist in the spiritual world in their perfect transcendental nature. Of course the way we describe them is limited by our material mind, body, senses etc. Therefore we cannot fully grasp the unlimited spiritual nature, but we can intuit, imagine, visualize or have a revelation of it. Therefore, we imagine Radha and Krishna to be persons because they are persons.
