According to many scientists we do not live in just one universe, but in many.
One concept I have believed since my early teens is that those universes are parallel universes, and that every decision we take moves us into one of an infinite number of parallel universes. I thought I was alone in believing this, but quite recently a number of physicists have come up with the same concept. This is perhaps still not quite mainstream science, but it is certainly no longer considered the loony fringe, and some scientists believe this is the only way they can explain some of the apparently contradictory evidence they have collected.
If you will excuse the pun, there is a parallel between the "multiverse" concept and the Schrödinger's cat concept which I explored in an earlier article (http://iwanttoimprovemyself.blogspot.co.uk/2015/10/schrodingers-cat-and-law-of-attraction.html).
What does this mean in practice?
What it means is that somewhere there really is a "you" who has achieved what you hope to achieve. That "you" already exists. If you are trying to get slimmer and lose five pounds, you have genuinely already done so. It is just that at the moment you do not recognize the fact. You cannot think it is impossible, as it has already happened anyway. You just need to catch up with the fact. If you are trying to develop into such a good, loveable person that you attract a really good and loveable partner, again just recognize that this has already happened. Not yet in this universe, but in another parallel universe. You simply need to recognize this person already exists and it can happen.
Imagine life is like a very large building with lots of rooms. As you travel through life you open different doors and enter different rooms. Each room you enter has lots of other doors which will lead you into lots of other rooms. If you think this sounds familiar, then perhaps it should. "My Father’s house has many rooms; if that were not so, would I have told you that I am going there to prepare a place for you? And if I go and prepare a place for you, I will come back and take you to be with me that you also may be where I am." (John 14:2-3, New International Version)
Some people might take this as an excuse not to do anything good in their life, taking the view that there will always be both good and bad futures no matter what they do. That is a bit like saying if you believe in reincarnation rather than in heaven and hell it doesn't matter what you do, as you can always come back another time and correct it. In both cases you would be missing the point. This "multiverse" has a lot of good in it, but also a lot of bad. You should want to open doors that lead to good futures not to bad ones. Why would you deliberately choose unhappiness in a bad future rather than happiness in a good one?
Notice how Jesus, in the quote above, says you can be where he is. I know most Christians would interpret that differently from me, but I interpret that as saying if we listen to our inner voice we will choose to open the right doors which will put us in exactly the right future for us.
The next time you are depressed with the lack of progress you have made, the next time you are pessimistic about what the future holds for you, remember this concept of "many rooms" in our "multiverse". Remember that a future exists where you have achieved all you ever wanted to achieve, and there is nothing to stop you opening the right doors to reach that wonderful future!
