To demonstrate how energy flows where attention goes, and how thought affects physical energy, pick up a chair by its seat and feel the weight of it. Then put it back down. Now focus your attention on the very top of the chair's back and pick it up by the seat again. if your focus is good the chair will feel lighter. Regardless of how you want to explain it, the practical fact is that if you have to lift anything you will find it easier to do if your attention is focused on the very top of the object or even in the air a foot above it.
