Why Muscle Testing Is Your Enemy And Why You Avoid The Truth Like A Plague? Muscle testing has been my main modality of getting answers from Source. I also get stomach lurch as a yes, nodding of my head as a yes when in a direct back and forth communication to Source, but the easiest and most straight forward way I get to decide if something is true or not, is muscle testing . I also know that a lot of people come to my site searching for muscle testing articles, so I decided to teach my core group students, the testers, muscle testing . Easy, I thought, we do it through a few webinars, and then I can sell our recordings, and we’ll make some money.
