Is it fear of the unknown or the fear of the ego not existing anymore? Good question. Both, I think. I'm not sure how to sort out the two. Can the fear be overcome by dissociation or putting on a mask? Not really. That's delusional. All we can do is face the fear and live our lives despite it. But that's not easy. That's truly heroic. That takes real courage, as Camus pointed out. Quite frankly, I don't know if I'm equal to the task. Who is?
