“So, dear Mr Kappus, you shouldn't be dismayed if a sadness rises up in front of you, greater than any you have ever seen before; or if a disquiet plays over your hands and over all your doings like light and cloud-shadow. You must think that something is happening with you, that life has not forgotten you, that it holds you in its hand; it will not let you fall. Why should you want to exclude from your life all unsettling, all pain, all depression of spirit, when you don't know what work it is these states are performing within you?”
