I believe that almost all our sadnesses are moments of tension that we find paralyzing because we no longer hear our surprised feelings living. Because we are alone with the alien thing that has entered into our self; because everything intimate and accustomed is for an instant taken away; because we stand in the middle of a transition where we cannot remain standing. For this reason the sadness too passes: the new thing in us, the added thing, has entered into our heart, has gone into its inmost chamber and is not even there any more, — is already in our blood. And we do not learn what it was. We could easily be made to believe that nothing has happened, and yet we have changed, as a house changes into which a guest has entered.
