The usual method of creation for most human beings is a three-step process involving thought, word, and deed or action. First comes thought; the formative idea; the initial concept. Then comes the word. Most thoughts ultimately form themselves into words, which are often then written or spoken. This gives added energy to the thought, pushing it out into the world, where it can be noticed by others. Finally, in some cases words are put into action, and you have what you call a result; a physical world manifestation of what all started with a thought.
All of us have our own inner fears, beliefs, opinions. These inner assumptions rule and govern our lives. A suggestion has no power in and of itself. its power arises from the fact that you accept it mentally.
