"Everything young grows old, all beauty fades, all heat cools, all brightness dims, and every truth becomes stale and trite. For all these things have taken on shape, and all shapes are worn thin by the working of time; they age, sicken, crumble to dust – unless they change. But change they can, for the invisible spark that generated them is potent enough for infinite generation. No one should deny the danger of the descent, but it can be risked. No one need risk it, but it is certain that someone will. And let those who go down the sunset way do so with open eyes, for it is a sacrifice which daunts even the gods. Yet every descent is followed by an ascent; the vanishing shapes are shaped anew, and a truth is valid in the end only if it suffers change and bears new witness in new images, in new tongues, like a new wine that is put into new bottles."

- C.G. Jung (Symbols of transformation)
