You do not think in a vacuum. Every time you have a thought, there is a biochemical reaction in the brain—you make a chemical. And as you’ll learn, the brain then releases specific chemical signals to the body, where they act as messengers of the thought. When the body gets these chemical messages from the brain, it complies instantly by initiating a matching set of reactions directly in alignment with what the brain is thinking. Then the body immediately sends a confirming message back up to the brain that it’s now feeling exactly the way the brain is thinking.
