I like this post very much, because I'm a fan of the teachings of Abraham Hicks. What Steve's writing here is nearly the same as Abraham teaches when they say: Get into the vortex. Get into alignment with your inner being, with source itself. Feel better as much as you can.
It's the same system, you get the same results, it's just differently called. Like someone already mentioned Tony Robbins, who teaches "the power of your emotional state", there are endless ways to explain this.
Steve, you've chose one of them and it's valid and great. You've written a nice and clear article. I'm curious if you have chosen the "scientific" perspective deliberately, or if that's just what you've felt inspired to do. Because you've could have written it from the perspective of spirituality, too.
Both perspectives are completely valid, each one is just more acceptable for different kinds of people. That's what I love about it: the message is universal and for everyone understandable.
