As you know, I’ve already read the book. My interpretation of what the authors write is that what you are experiencing/creating is a human universe and that you also give it meaning.
I see that you are asking for the meaning of it all as if there was an answer out there, an “objective meaning”, for us to find through continued research out there. But if we ourselves are that pure consciousness projecting that which we call the world, and if there is a meaning to this process, then the meaning will be given/created/projected by consciousness too.
I guess I’m trying to say that you are the universe and the meaning-giver 🙂
I can’t wait for you to read the book and let me know what it means to you!
