We join spokes together in a wheel, but it is the center hole that makes the wagon move.We shape clay into a pot, but is the emptiness inside that holds whatever we want.We hammer wood for a house, but it is the inner space that makes it liveable.We work with being, but non-being is what we use.
When one door of happiness closes, another opens; but often we look so long at the closed door that we do not see the one which has been opened for us.
Helen Keller
