Enlightenment is mental concept that you created to escape from your own life and suffering. It is like a carrot that you keep in front of yourself and chase after it endlessly, not seeing that you are like a dog chasing its own tail. True enlightenment is the realization that there is nothing to chase after. Nobody can give you enlightenment, it cannot be obtained by following the light of another, you have to find the light in yourself. I do not believe ET can bring you to enlightenment, he might or might not be enlightened himself. Maybe he just created some illusion for himself, got trapped in his own illusion, and he manipulated thousands of people into following his illusion. What can he offer you except for leading you away from yourself? Enlightenment is understanding yourself, your own nature. Everything is in you, you do not have to search for anything externally, your own mind is enlightenmet.
