Whenever I get up in the morning, I always think to myself, "Am I really the same person I was yesterday?" For example, just as a computer loads its OS into memory and boots up each time it restarts, is it possible I'm just booting up the person called "Saikawa Sohuei" each morning and trying to play that role?
Seeing nature and thinking it's beautiful is what's unnatural. That means the life you lead is an unclean one. If you can cut yourself off from mother nature and still survive, doesn't it mean you have enough inner beauty to allow you to do that?
