Maurice Maeterlinck said this quote

We believe we have dived down to the most unfathomable depths, and when we reappear on the surface, the drop of water that glistens on our trembling finger-tips no longer resembles the sea from which it came. We believe we have discovered a grotto that is stored with bewildering treasure; we come back to the light of day, and the gems we have brought are false – mere pieces of glass – and yet does the treasure shine on, unceasingly, in the darkness!
