Deep sleep is the closest thing to self-realization that there is. Did you ever wonder why, when you come out of deep sleep, you say, "I feel good?' There is no one who comes out of deep sleep that feels bad. You may have a bad dream. But I mean when you are really in deep sleep and you wake up, if you catch yourself, you will see you feel good. You feel great. You feel wonderful. It's only when you start to think that the feeling changes. Check it out for yourself. Why? Because deep sleep is really bliss. Yet it's unconscious bliss. Liberation is conscious bliss. Liberation is when you're awake and you're conscious. You're not conscious of anything in particular, you're just conscious. That's liberation. (Robert A.)
