Stephen Levine teaches meditation. For many years, he counselled the dying and the grieving, and he's written a number of books on the subject. I asked him about the underwater feeling I had experienced. Well, there is a physical feeling of pressure, I think. I think that it's almost universal.
Some people talk about being crushed or bent under grief.
I think there's a physical feeling of pressure when loss is that great because it's a little bit like the pressure that occurs when a vacuum is first broken. There's nothing to rush into it. That which rushed into it is gone. And so, you're left with the wanting of the rushing, the emptiness, the pressure. Many people have spoken about walking under the ocean, feeling as though they were walking under the ocean.
