We cannot know that we are illuminated by a great light simply by looking up into the sky. But if we lower our heads and look down at our feet, we can clearly see the long, dark shadow that stretches out from us. We know that the darker and blacker that shadow is, the brighter is the light that shines upon us. Thus, we have been told to look at our own dark shadows [within].
~ from TARIKI: Embracing Despair, Discovering Peace by Hiroyuki Itsuki
Klee died relatively young and his style changed as the inevitability of death became inescapable. With great seriousness in one of his last paintings, Klee announces that death is a purifier, like fire, and a means to fulfillment. This is the once terrible, seen as the most beautiful. This is the real power of joy, to make us certain that beneath all grief, the most fundamental of realities is joy itself.
