When the mind is darkened, it is not that a light was taken from you. It is that you have become so identified with your thinking that you no longer feel the living presence beneath it. This is what that old word ignorance truly means, not a lack of facts but a forgetting of who you are.
Cut off this way, you feel alienated and alone in a hostile world. Yet nothing has severed you from life. The heart has only grown hard around its own thoughts. The moment awareness returns and that hardness softens, the sense of separation ends, because you were never truly cut off; you had only lost yourself in thought.
