I learned this on my first acid trip. Nature is more intelligent than your average person believes, and it sucks that we take it for granted. I wish more people would open their third eye and pay attention to their surroundings.

EDIT: To add to the "there is so much we can't observe" thing, I implore anyone reading this to google the Electromagnetic Spectrum. Our senses, specifically sight and sound, can only pick up a tiny sliver of what's out there. You don't even need psychedelic drugs to understand just how little we can observe as human beings if you understand how radio waves work.
