na. 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 televi-
sion screen produced by the greatest television produc-
er in the world cannot provide such a sharp image for
you. This is a three-dimensional, colored, and extreme-
ly 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, whereas with your eyes, you watch a three-
dimensional perspective with depth.
