The philosophy says that when summing life up in just a few words or sentences the world and or life is not that great but it is when you think about the world and or life in depth and look back on times when it was good that is where the perfection comes in. So basically what makes the world perfect is solely thinking about the good times. There is nothing to really compare this to in the weren world because average westerners are way less spiritual and all philosophy-like like easterners are.
