When you see something you don't just use your eyes alone, as you know... You use your mind aswell...
But beyond this, your eyes and ears both affect your mind, so your hearing, indirectly, affects your vision...
An example of this is when someone says they need to be able to look at you to hear you properly (which may involve wearing eye-glasses)...
So basically all the senses affect and enhance eachother...
An example of this is looking at someone talking and reading their body language and following the movement of their lips...
Hearing and smelling with an eye to detail...
Tasting the spoken words...
Feeling what someone is saying...
The mind has an important part, the general movement of the body (particularly the head) plays a part too...
Do you see where I am coming from?
Questions... Do you think the relation of different senses makes that much difference? Or, is the relation negligible to the point, where they relate so minimally that they're entirely independant? And, does these thoughts make any difference to how you think you do, and can, operate?
