If it is true that the way we perceive the world around us shapes our reality, then our mind determines our position towards the world around us. The reality that we seem to be so sure of is in fact a very relative matter. A single piece of reality may be perceived as three different forms of interpretation by three different observers. So if the reality is so relative, then the way our mind looks at each event, would shape our understanding or experience of that moment. It is like our mind shapes our understanding of our realty. Once we accept this, then we can understand that if my mind shapes my experience of reality, then by changing my mind I should be able to experience a different version of the same reality. So by changing our mind we can have a changed experience of our world.
It may be difficult to imagine any change in reality when we deal with severe debilitating chronic pain. But the fact is that we are able to handle the same debilitating pain better when we are in a better mood. We may be less irritable and more tolerable at the same life circumstances in different times or moods. The way we think affects the way we feel and our feelings affect our body sensations. So pain sensations can be intensified by negative thinking. This is the basis of cognitive therapy. In cognitive therapy the therapist tries to change the way one thinks about an event. Once the outlook of patient to an event changes, the feelings would change as well. The changed feelings would affect the body sensations. That is how one would change the experience of their world by changing the way they think.
