The world can be a confusing place. Don’t even try to figure it out or you’ll go crazy. Instead, just realize the way it is. There’s some questions you’re never going to get an answer to, and some you don’t need to know the answer to. Life doesn’t make sense. It’s happenstance, it’s random, its accidents, with a little karma thrown in for good measure. Figuring it all out is not an option. You’d have to live 5000 years and I bet you still wouldn’t get it. Just ride the Dao. Let things be as things will be.
