“People say that what we're all seeking is a meaning for life. I don't think that's what we're really seeking. I think that what we're seeking is an experience of being alive, so that our life experiences on the purely physical plane will have resonance within our innermost being and reality, so that we actually feel the rapture of feeling alive.” - Joseph Campbell

“’Spirit’ comes from the Latin word ‘to breathe’. What we breathe is air, which is certainly matter, however thin. Despite usage to the contrary, there is no necessary implication in the word ‘spiritual’ that we are talking of anything other than matter (including the matter of which the brain is made), or anything outside the realm of science... Science is not only compatible with spirituality; it is a profound source of spirituality.” - Carl Sagan
