Tom did post this a while back that is also relevant to the conversation as to undesired processes resulting in the manifestation of your intent.
Consciousness is primary, actual, and fundamental while PMR (your body) is virtual -- a derivative of consciousness. This is the phrase to remember: The mind leads and the body follows. However, within PMR, body and mind are also part of an interactive system that must globally obey the defining ruleset -- at least to within some sufficient amount of uncertainty. individually, the ruleset can be subverted up to the point that a more global statement is being made.
Thus, if a strong, clear, well focused intent says: I want to quit smoking. Or, I want to be much thinner and lighter than I am now. then, because the mind leads and the body follows, the body that is led by that intent will most certainly quit smoking and lose weight -- but not magically. The psi uncertainty principle requires a process with enough uncertainty to globally discount psi as a necessary ingredient. Thus such intent may cause one or more things to happen: appetite is lost or curbed, metabolic rate is increased, one feels more inclined to take the stairs rather than the elevator. If normal nudging does not succeed with the first and the third, then schedule or sickness will force the skipping of meals, the elevator will not be working, the car will break down or friends will suggest walking together after lunch.
You or your wife or children will become allergic to smoke, other peoples smoke will begin to annoy you and smell bad, people with cigarettes begin to look childish and stupid, your best friend and your mother will both get terminal lung cancer, your workplace will ban smoking, you will suddenly realize that you are drug addict just like any other drug addict and not like the feel of that truth, the price of cigarettes will go up and you will lose your job. You begin to realize that people think less of you and avoid being around you because you smoke. You come to realize that he people you would most like to associate with are mostly non smokers and that people who smoke aren't as pleasant to be around and appear to have more issues and personal problems.
A weak, foggy or unfocused intent does the same thing but the results and effectiveness are also weak, foggy and unfocused. Results are poor
The bottom line: The virtual reality will conspire to follow a powerful intent within the bounds of psi uncertainty as long as all involved/affected sum up to a long term optimized path (gain) for the system with no significant Big Picture loss for any individual.
