How can you be sure that your "new" technique actually accesses the anscestoral limbic brain, I mean it makes sense but are you just making a creative educated guess? I'd like to see some scientific explanations.
I'm not attacking you I actually think it makes good sense, for instance if you really focus on a goal and ask yourself, "do you really want this?" Yeeessss!!! Could work.
Also being a musician I often find that when I believe in something it's much more powerful to scream in song the message you're getting across.
