Tom Robbins said this quote
“ There are landscapes in which we feel above us not sky but space. Something larger, deeper than sky is sensed, is seen, although in such settings the sky itself is invariably immense. There is a place between the cerebrum and the stars where sky stops and space commences, and should we find ourselves on a particular prairie or mountaintop at a particular hour, our relationship with sky thins and loosens while our connection to space becomes solid as bone. ”
