" Out-of-body exploration provides substantial evidence that we are evolving beyond the dense limits of matter. Is it not possible that some other species may have already achieved this evolutionary leap? I contend that all life-forms are slowly evolving beyond the need for biological form. Eventually we will recognize and consciously explore our multidimensional nature and take our place in the magnificent thought-responsive realities of the universe. "
