The only "energy" involved is whatever thought and effort you invest in it. If you think something is true, or that something can be done, you're much more likely to search for ways to make it happen. If you don't think something is true or can't be done, you don't invest and move on to something else.
That's plenty powerful without believing in any kind of external, supernatural influence. That bit about "confused or mixed thoughts" is simply rational learning through deliberation, and it's a good thing if you get more than a single other perspective. I would hesitate a lot to call that guy's friend. It sounds like he wants confused people with mixed feelings so he can tell them some kind of Truth. Fertile fields for planting, I think the Bible calls it.
