“Connection with the world is built in to every aspect of our being. […] We’re joined to the cosmos and the everyday world as described by science in countless ways: the elements composing our bodies are the products of the Big Bang and stellar evolution; most of our DNA is shared with other beings; our perceptions and sensations are all mediated by processes involving photons, electrons, ions, neurotransmitters and other entirely physical entities; and our character and behavior is fully a function of genetics and environment. We are, therefore, fully linked with our surroundings in time, space, matter/energy, and causality. In fact, no more intimate connection with the totality of what is could be imagined. So, from a naturalistic perspective, there is an empirically valid referent for the sense of cosmic consciousness encountered in spiritual experience. The feeling of unity generated by (actually, identical to) the quieting of the orientation mechanisms in the brain mirrors the objective state of our complete interconnection with the world.”
