Interesting!  I like a lot of this.

What's your definition of unconscious/subconscious?  Is what you call unconscious or subconscious experience in #7 the state you need to be in to experience the fact that the ego is not real?  I experienced #1 in meditation, but wouldn't call that state unconscious.  This may amount to arguing over words though.

I'm not sure about the part on free will.  It's possible that preferences aren't real in the way we think they are, but that we still make some decisions.
