“OK Matt, so, I sat and meditated for twenty minutes, and nothing happened.”
Nothing is exactly what’s supposed to happen!
Of course, I’m sure something happened, such as, you had some thoughts, feelings, and sensations.
But no aliens are supposed to descend from the sky; Buddha is not supposed to materialize in the room and congratulate you.
Is is possible that you might have a moment of clarity or, dare I say, enlightenment?
Of course. I can’t say who will, or who will not.
What I can say is that nothing specific is supposed to happen, perhaps other than you actually making the time to actively do nothing.
Then, just let whatever might happen, happen.
