When you become so determined that you want to feel good - you have become as your Inner Being is, in such a pure place of Positive Energy - then that which is 'negative energy' simply can't mix with you. It defies Law. If you are very strong and clear about your positive wanting, and feeling it, then 'bad' things simply cannot get in. Colds can't get in, car accidents can't get in, anything that you are not wanting cannot be your personal experience.
Esther Hicks..... if we were talking to you on your first day of physical life experience, we would say to you, "Welcome to Planet Earth. There is nothing that you cannot be, or do, or have. You are a magnificent creator. And you are here by your powerful and deliberate wanting to be here. Go forth, giving thought to what you are wanting, attracting life experience to help you decide what you want and once you have decided, giving thought only unto that"
Esther HicksA belief is only a thought that you keep thinking. So as you keep thinking this thought, you keep vibrationally attracting relative to that thought. So you confirm your own beliefs again and again and again and again and again. That's why someone who believes in cancer can confirm that belief, or someone who believes in robbery can confirm that belief. So everything is a sort of confirmation of belief.
