Query: Who says?

Don't any of you who rated this 5 stars ever stop to say, "Oh, yea? Who says?" Even as one who is "already indoctrinated into the received wisdoms of the New Age" and one to whom much of Gary Zukav's theories sound reasonable, I can not take his total lack of support for what he posits. Not so much as a personal experience or reference to anything in the wisdom traditions. We have Guides and Teachers? Why not just Teachers, or Guides for that matter. Why not Junior and Senior Teachers, and Guides, Angels, and Fairies? Where did he come up with this stuff? ... I can't help thinking this would never had seen the light of day if it hadn't come from the Dancing Wu Li Master guy.
