The abyss of unbeing — Proust.
Oliver Sacks calls what Proust is describing as what it feels like when the very foundation of perception, of consciousness, of self is undermined. Then again when Hans Solo was frozen in carbonite he called the experience, “That carbon-freeze was the closest thing to dead there is. And it wasn’t just sleepin’. It was a big, wide-awake nothing!”
Now if that happens on any kind of regular basis go see a doctor, but if this abyss happens once in a while you just might take advantage of it. When we meditate we try our best to empty ourselves and become open to what comes. What new journey the abyss brings might be a signal of what path you should follow or not.
My point being is that we need to be alert to signals our body and brain send. I am not very good at this, but I am trying to be better at being more conscious, more aware. The world has a lot to teach me, and I don’t need to be asleep at the wheel.
