Antz, I've had similar results after my first Labyrinth experience. When I read your words they seemed very eerily like my own. I don't profess to have received anything from it nor do I deny what I may have received. I will point out one red flag I saw in your words above. You wrote, "So what do I need to do differently to make the Labyrinth exercise work for me?" I heard Paul say in the program (I paraphrase because I don't recall the quote and do not desire at this moment to go find the words) It's more important to ask, what must change to allow the manifestation? I get the sense it is very much like Obiwan's advice echoing in the mind, "Trust the force, Luke."
After photoreading a book, we say, "I am curious how my mind will manifest the knowledged gained from this book in my daily life." The affirmation assumes what we do not consciously know at that moment but sets the expectation.
