You don’t have to do anything. Enlightenment is not your doing. And it is not a gift. You already are enlightened, just you have not looked in the right direction.
The difference between the enlightened being and the unenlightened is not much; it is negligible. One has looked into himself, the other has not looked into himself. This is not much of a difference. At any moment the other can also look into himself. Perhaps when your eyes are tired of looking outside, you close them in utter boredom and tiredness and look inside.
You have searched much and found nothing outside. You look in and suddenly all that you were seeking is already there. You have come with it into the world, it is your intrinsic quality.
and the grass grows by itself.
