The last teleconference call with Dr. Randine Lewis was on the Hypothalmus a part of the brain that is the governor or emotional interrupter of your body, so if you are in discord, the body will set up blockages.  Fear contracts or locks in stress and holds the reproductive system in a static state.  When we want to "Make things Happen" this often releases stress hormones in the body whereas when we are in a state of acceptance there is no need to strategize, you then come from a state of allowing.  This is why you cannot think yourself into better fertility.
