Enlightenment is not a place to get to: it is a state, it is a relationship to existence, that exists outside of duality, outside of right and wrong, outside of time, outside of comparison and outside of competition.
In spite of what everyone says, enlightenment is not something that you arrive to and then you are set for life.
I have entered the Buddha yesterday to feel him, and experienced an 80% on 20% off state: to stay in the ego-less state where even the observer, the witness disappears takes work. It takes returning to the present moment again and again and again.
In one of my favorite tales about the Buddha, a man, angry at the Buddha, screamed at him, spit on him. The Buddha’s disciples wanted to teach the intruder a lesson, but the Buddha stopped them.
The attacker left and the disciples expressed amazement at the Buddha’s ability to not get upset, to be totally egoless.
He said, that being egoless is like a light-bulb (obviously he used another way to explain, but I don’t remember what he used exactly… there was no electricity at that time, 3500 years ago, lol). The light bulb seems to be lit all the time. But if you looked at it in a time-lapse movie, you would see that the light is interrupted with brief moments of no light: continuous light is an optical illusion. And so is ego-lessness.
