Never stopped. And I don't wish to stop.
Because I know that I am a spiritual child of God with a temporary, Homo sapiens body. I've been outside of my body (effectively a ghost). I have seen the world around me without the need for human eyes.
Most "ghosts" are unaware of their surroundings. They exist in the "darkness" talked about in the Bible, brought on by the poison of the forbidden fruit -- ego, in all of its action-reaction dichotomies.
I long for the light of truth wherein my spiritual eyes will once again be opened and I can see the universe on a more permanent basis. That way, when this human body dies, I will have continuity of consciousness -- effectively, everlasting life through Christ and God.
