You may have seen the film 'The Secret' by television writer and producer Rhonda Byrne or, perhaps, another related movie, 'What the Bleep' by William Arntz.
Both of these movies deal with the subject of quantum physics and the ability of the human brain to affect our current reality.
Many people refer to this capability as the Law of Attraction.
The basic idea - that is possible to change our experienced reality by changing our thinking - has been around for centuries.
Similar ideas were advanced by the writers of New Thought; people like Napoleon Hill, Wallace D Wattles and James Allen all wrote about the ability of the mind to affect reality.
What both of the above movies attempt to do is to make the case for the basic New Thought hypothesis, but by bringing the argument right up-to-date, in particular, by referencing the ideas to be found within quantum physics.
According to quantum physicists, the sub-atomic world really is a magical place where it can be observed that matter - the essential stuff from which we are all made - behaves extraordinarily.
Everything we know and understand about reality at the level we experience it, is turned on its head in quantum theory.
Experiments produce astonishingly counter-intuitive results.
As the scientist and Nobel prize winner, Neils Bohr commented, "Anyone that is not shocked by quantum theory doesn't understand it.
" Essentially, science has show that matter and energy are different manifestation of the same basic stuff.
Energy can be turned into matter and vice versa - matter can be transformed into energy.
We are composed of matter and we are therefore also energy; and by thinking, we, ourselves, do actually change.
What is, perhaps, an even more exciting idea, though definitely still somewhat controversial, is the notion that we can also change things outside of ourselves.
There are certainly opponents to the proposition.
But those who actually use the principle to produce positive change within their personal lives continue to provide, at least, anecdotal evidence.
One way of thinking about this interesting cause-and-effect mechanism is to recognise that our thoughts certainly do control our attitudes; and our attitudes affect our personal behaviour.
So, reasoning forward from there, we can easily see that our behaviour, or actions, are directly responsible for producing the tangible results we experience in the physical world.
Hence, it can reasonably be argued that our thinking does indeed produce changes in our reality.
Learning how to use this powerful concept to impact our lives is how you can indeed change your life simply by changing your thoughts.
