When we are in love, our love is too big a thing for us to be able altogether to contain it within us. It radiates towards the beloved object, finds in her a surface which arrests it, forcing it to return to its starting-point, and it is this shock of the repercussion of our own affection which we call the other's regard for ourselves, and which pleases us more then than on its outward journey because we do not recognise it as having originated in ourselves.
