I believe the differing religions is a reflection of trying to explain the unexplainable - inner experience really can only be explained via allegory. It's like trying to explain the color red to someone who is color blind. How can one even begin with that?

To say that "spiritual experience and God can never be grasped with the mind since it is so vast", to me, is not a statement of arrogance and righteousness or a hall pass for the "intellectually lazy".
