The funny thing with "enlightenment" is that at the state of enlightenment, you realize that everyone is enlightened.
With that said enlightenment is the knowing of one's true Self of believing Everyone knows their true Self even if they seem to have forgotten and claim they do not know. So, again enlightenment is not something we become, but that which we are. Then in real terms, you wish for others what you wish for yourself. In other words, you see no difference in your soul and others' soul. If you can achieve that, it would be as good as enlightenment. And finally “Enlightenment” means to me faith:
You start seeing God in self and start seeing self in everything else, animated or in-animated.
