The Body - Eyes and Vision

The mind associates inputs that we get from our 5 senses,which could be said to be the antenna of our minds.  It is the body that produces these signals and relays them to the mind. What we see is not what's there, but our brain's interpretation of what we think we see. This is why everything and the life people live is mostly just in their heads, not outside of themselves, and where the metaphor for the matrix at a basic level comes in. Everything by that understanding is a projection.

The body is far more complex than just the organs responsible for the 5 senses, but I will start with those.

Visual sight

The first organ in the body I will talk about is the eyes.. The visual cortex of our mind in the occipital lobe is what constructs the image in our brains but only based upon the signals given through our eyes. The eyes interprets light waves that hit. Sometimes the mind can give ourselves a false reading which causes hallucination or seeing something that isn't visible to others. But I want you to not rule out that perhaps some can learn to see what would otherwise be filtered out by most through the visual system.

This lack of actually seeing what's there and instead just seeing a representational system that appears to be what we are seeing is what causes optical illusions.  Our minds literally will tell us something is different then it really is. We will see two exact copies of color look like white and black when they are both gray due to the illusion of shadow and light.

The above image the A square and the B square are exactly the same shade. Our mind attempts to compensate for the context of their being "shadow". But in reality a shadow merely makes things appear to be darker than they are. In a drawing we can't caste a shadow on paper and instead must darken the shade. In drawings they actually ARE darker than they appear.

Many will think this is a trick, so do this for yourself. Copy it into microsoft paint and circle the squares and bring them over, or else use the find the color tool and draw two lines for each color. They are the same. Your mind is not seeing things as they are but attempting to compensate for shadow that isn't there.


Illusions especially works with 2 dimensional images but can also work in what we perceive to be 3-d reality.

(brain games on the history channel features many illusions like this and many others)
