No I think it is a matter of the brain experiences, however beliefs are from the brain and so are the main contributing factor to the experience expected to be had. Furthermore the brain interprets the experience based on the beliefs held about the experience.

In this light we can see that everything about experience happens in the brain. The creative process is colored by the materials provided to create. Example give a child a coloring book and only two crayons, one blue and yellow, you can pretty much predict the picture will be blue and yellow because that is all the colors you have provided. The child may see three choices, white paper being the third choice. Now if he is willing to expand his mind more the possibility of shades comes in. Now even more mixing the colors he finds many types of green. Even with all of these expanded choices he is still limited by what he has so even in this freedom he is limited and can only expand so far. It is not until he receives other colors that he can expand beyond what he has.

Give a child Lincoln Logs to play with and you know he will build some kind of cabin because that is all you can build with Lincoln Logs. The same way we create experience by the materials we keep within our minds of possibility, if we only believe we have limited possibility we can only have limited possibility. We can not see any farther than we are willing to look and if we do not believe there is anywhere else to look we will only see what we are wiling to look at as the only choice there is.

We may try to get into a store building and find the door locked, we can give up and say well they must be closed today, then we return and find again the door locked we could do this again and again until we give up and say they are never open. That is one choice we could also go around the building and find that there is another door propped open with a welcome sign on it saying "OPEN."

It requires us to choose to think of other possibilities than we see before us. It requires us to think of the same situation from not our perspective, but what would this mean to others if I were this person or that person. In so imagining this we can come to great understanding but as well we can see the futility of our choice of experience over something. It can even become ridiculous to the point of laughter over what we were choosing to believe.
