It seems to my unscientific mind that it - my "mind" - is really just the processing done by my brain.
The processing done by your brain can be changed. The course that you send your thoughts through can actually be altered. I'm trying to explain it in the most elementary terms of course.
An example of this is being able to change the context in which you view an experience. Our brain associates things to past experiences, so you may habitually see something as bad. But, if you look at your past experiences in a different context, you will then habitually look at the new experience in the context you have put your past experiences in. Hope that's not confusing.
