"That which is not present in deep dreamless sleep is not real." -Ramana Maharshi

Ken Wilber references this quote in a journal entry. It's an amazing idea. I don't know what real means. But if you just imagine what is present (from the point of view of your interior consciousness) when you are in dreamless sleep, and think of that as being something that is present always, it's pretty amazing. It reminds me a little of when I would get really high and things would start to look like a surface, a film with basically no substance. That was a little scary actually, because it was like I was seeing through things to something else.
