"Any thought or notion that arises in the mind is provoked by an outside stimulus for which the corresponding image or substance is evoked from memory. This is how thought is born. Thus, the reality of any object, whether as near as a chair or as far as a star, stands only as an image in the mind. And mind being nothing but the content of consciousness, where there is no consciousness, there is neither mind nor universe."
~Ramesh Balsekar
