I think the audio/visual portion is only part of the process. Aaron himself has said that hardware is needed to maintain some special thing running 24/7, and I think that is what is actually translating intentions into universal code and sending it into the personal subconscious and collective unconscious.
Anyway, best thing is to judge by results. Has other programs been any more successful, given the time/money commitment you put into them?
I'm fairly convinced it works, based on my unfortunate but immediate results, lol
