Have you seen or read The Secret, or maybe some older classics of positive thinking like Think and Grow Rich, by Napoleon Hill? These and countless other books, videos and seminars talk about something called the Law of Attraction, which says that we can attract whatever we desire with our thoughts.
There are also nay-sayers who deny that this is true. They say, "if it was so easy to create your own reality, why are so many people sick, poor and unhappy?" Who would choose such a reality? Even many people who believe in the ideas of positive thinking and the Law of Attraction are secretly afraid that it's just too good to be true.
My own conclusion is that the Law of Attraction IS true, but that there is a sort of catch. This is the fact that many of us have unconscious blocks that go against our conscious thoughts and desires. We may even secretly believe that we don't deserve money, health or some other form of abundance.
Negative subconscious beliefs, that may have been with us since early childhood, can be difficult to overcome. Our conscious desire for prosperity, for example, can be thwarted by an unconscious belief that we don't deserve it. These negative beliefs don't have to make sense to block us.
There is a simple technique that allows us to almost instantly remove blocks. It is called EFT (Emotional Freedom Technique) and is based on the Chinese system of acupuncture (no needles though!) combined with modern psychology. It is so simple in fact, that many people are skeptical that it can really work --until they try it.
EFT works by having us tap various points on our body. This sends energy through the meridians (pathways that energy follows through the body). Tapping is combined with certain dialogue, which can be spoken out loud or to oneself. These are something like affirmations, but more sophisticated in that they are not only positive statements, but a removal of negative beliefs.
Tapping has been used to treat many kinds of conditions, both physical and psychological. One EFT expert, Brad Yates, has created a system that works especially at removing blocks to abundance. This is actually so fundamental that it really includes just about every aspect of our lives --if we feel abundance, we may get more money, but we also end up having better relationships, better health and so forth.
