One lucy trip triggered a year-long "trip" of its own that has brought me a completely new perspective to see reality from. The LSD trip didn't teach me anything MAJOR on its own, but it gave me a strong and loving shove in the right direction.
Not sure if anyone said this already, but I learned that All is One. :D Life and consiousness don't follow different rules than the rest of nature, we are subject to cause and effect and ought to seek equillibrium with our environment, which shouldn't be hard because it is us, and we are it.
The thing that makes humans special, when compared to other Earth animals, is that we have the power to choose what energy we put into this system. And it's baffling that we all don't just pour love and compassion into our reality, and enjoy the intensified echo of positivity that would ensue. The reason we don't all automatically do this, is the ego. The illusion that we are separate from this system, that we are separate from anything. We all possess the knowledge of right and wrong, good and evil. It is inside of us already, it needs not to be taught. This is what really turned me away from Christianity, which teaches the idea that human suffering comes from humans trying to see good and evil, a bit counter-fucking-productive there.
This has been the hardest point in my life, but also the happiest part, with the clearest sense of direction. I've been living my life wrong all along, and now I am trying to turn this motherfucker the other way. That's a hard thing to do, because most modern societies directly combat this way of thinking.
