BASIC TENETS OF ISLAM

Before passing on to the subject of the eye, let us briefly answer
the question of how we see. Light rays coming from an object fall
oppositely on the eye's retina. Here, these light rays are transmitted

into electric signals by cells and reach a tiny spot at the back of the
brain, the "center of vision." These electric signals are perceived in
this center as an image after a series of processes. With this technical
background, let us do some thinking.
The brain is insulated from light. That means that its inside is
completely dark, and that no light reaches the place where it is

located. Thus, the "center of vision" is never touched by light and
may even be the darkest place you have ever known. However, you
observe a luminous, bright world in this pitch darkness.
The image formed in the eye is so sharp and distinct that even
the technology of the twentieth century has not been able to attain
it. For instance, look at the book you are reading, your hands with
which you are holding it, and then lift your head and look around
you. Have you ever seen such a sharp and distinct image as this one
at any other place? Even the most developed television screen

produced by the greatest television producer in the world cannot
provide such a sharp image for you. This is a three-dimensional,
colored, and extremely sharp image. For more than 100 years,
thousands of engineers have been trying to achieve this sharpness.
Factories, huge premises were established, much research has been
done, plans and designs have been made for this purpose. Again,

look at a TV screen and the book you hold in your hands. You will
see that there is a big difference in sharpness and distinction.
Moreover, the TV screen shows you a two-dimensional image,
