Got it!
It's memory...memory of harmony. Memories we stored unconsciously when we were at our very best, and innocent.
And genetic memory...cellular memory of all the conditions that best suited our kind, over generations, whether or not we understood with our 'thinking' minds.
Our 'thinking' minds deal in possibilities, an endless variety of possibilities...jumping around from idea to idea...providing us with scenarios and visions and perceptions...while also limiting, constricting, and shaping the flow of energy through our individual lives/bodies.
Release that grip on ourselves, relax our 'thinking' mind's insistance on 'control', while keeping to our best principles of harmony, allowing the fullest flow of energy possible.
'Healing' is, then, only one of the benefits we can experience. 'Happiness', contentment, fulfillment, satisfaction, and peace, are others.
In other words, in my opinion, get our 'thinking' minds out of the way of free-flowing energy, set our intentions on harmony, and it may just happen.
We don't have to figure out 'how'.
'How' will just occur to us, without 'fighting' or 'striving'.
