I recently read an interesting essay on perspective in which the author confessed the startling realization that he has no head. He looks down and sees feet, legs, a stomach, and chest, but where his head should be is the whole world. There are trees and a sky and all types of other amazing things. He muses that if he has no head he can hardly be human.
Certainly, it's just a thought exercise, but a healthy one I think. It's an exercise that can better lead to life in the moment, to looking at things in a new way and a departure from what is so imbedded. It reminds me of the first time I was able to convince myself that my eyes were projectors as opposed to cameras and that everything I saw was being created by my own mind. It may sound silly to those who aren't accustomed to thinking about things in a different way, but really, there is no more proof that the world is being interpreted instead of being creating. Everything we know, after all, is only reactions in our brain regardless of our opinion on what is really happening.
Typically, we think of the brain as a computer interpreting what it gets through its camera (eyes), ears (microphone), and other senses, but it can also be looked at as if our eyes were not a camera but a video screen and the brain was projecting what we see, hear, and feel. Both perspectives are true since our brain interprets sound waves and lights rays much like a computer interprets code before coming up with an end product.
Think of how differently people perceive things based on their mental abilities, their knowledge and attention to detail. The level to which I pay attention and remember is based on what else I have going on in my life such as upcoming travels and bills. This is why it's so important to fine tune ones brain in a desired manner.
