The only sadnesses that are dangerous and unhealthy are the ones that we carry around in public in order to drown them out with the noise; like diseases that are treated superficially and foolishly, they just withdraw and after a short interval break out again all the more terribly; and gather inside us and are life, are life that is unlived, rejected, lost, life that we can die of.
It's no good trying to get rid of your own aloneness. You've got to stick to it all your life. Only at times, at times, the gap will be filled in. At times! But you have to wait for the times. Accept your own aloneness and stick to it, all your life. And then accept the times when the gap is filled in, when they come. But they've got to come. You can't force them.
