Roughly a quarter to one-third of human existence is nothingness, e.g., sleep. You close your eyes, and time ceases, “you” are without any conscious awareness, problems vanish, and then, just like that, you awaken, and “you” appear out of nowhere, and “what was” piles back on to your suddenly realized self.
Where did “you” go when you fell asleep? What are “you” when your body sleeps and consciousness has disappeared? Is this your state before you appeared on Earth? If you can say you don’t know. If you know, you can’t say.
Still, it seems the most incredible peace offered by awareness lies in being completely unaware. Who knows? But thank goodness for those periodic spells of unconsciousness.
