" We can all intellectually understand that the brain can manage and regulate many diverse functions throughout the rest of the body, but how responsible are we for the job our brain is doing as CEO of the body?
Whether we like it or not, once a thought happens in the brain, the rest is history. All of the bodily reactions that occur from both our intentional or unintentional thinking unfold behind the scenes of our awareness. When you come right down to it, it is startling to realize how influential and extensive the effects of one or two conscious or unconscious thoughts can be.
For example, is it possible that the seemingly unconscious thoughts that run through our mind daily and repeatedly create a cascade of chemical reactions that produce not only what we feel but also how we feel?
Can we accept that the long-term effects of our habitual thinking just might be the cause of how our body moves to a state of imbalance, or what we call disease?
Is it likely, moment by moment, that we train our body to be unhealthy by our repeated thoughts and reactions? What if just by thinking, we cause our internal chemistry to be bumped out of normal range so often that the body’s self-regulation system eventually redefines these abnormal states as normal, regular states?
It’s a subtle process, but maybe we just never gave it that much attention until now. "
