The Kingdom of God is within you. What does that really mean?

You seek the Kingdom of God somewhere ahead, as if it were a future goal. But Christ said, "The Kingdom of God is within you." This is not a reward after death. It is not a state that appears or disappears. "Within" does not mean deeper inside yourself — it means below yourself, where there is no longer an "I," no observer, no separation. The seeker and the sought have never been two.
