“Real happiness is invisible. It is freedom itself and that means that happiness is not determined by the feelings that happen, but by standing apart from the feelings. Exactly as the sky is not influenced by the clouds passing by at a certain level, and entirely independent of whether they are beautiful or ugly clouds. Space remains space, and in our comparison that is happiness, the space that remains unmoved even if such ugly clouds are drifting by.”

— Wolter Keers
