Normal Is Great
Enlightenment could be a thing of the past. By the old standards, most of us are probably enlightened or more. Smarter too.
I say this because children understand gravity and teenagers understand that E=m, maybe they don't understand the maths, but they intuitively know. Einstein got there by intuition, the maths came later. Lau Tzu got there by intuition (he never read a book on it), Buddha too. In those times, there were many people who didn't get these things, they thought that angry gods brought rain and famine, that the world was flat and things moved down.
Now we don't, we're generally more enlightened than before. We don't on the whole believe in gods, we do have more intelligent concepts for things than we used to. This is said even given that in a few years we will be exposed as dumb by new thinkers, for now though, we're good.
What is this enlightenment people seek, what is this perfection, this release? Just exposure or admission of an inner imbalance? Not to worry, that's being human.
