ETERNITY HAS ALREADY BEGUN - Islamic Books, Islamic Movies ...

your olfactory center. You can never have direct contact with the
original sight or smell of that rose that exists outside.
To us, the "external world" is a collection of the electrical signals
reaching our brains simultaneously. Our brains process these signals,
and some people live without recognizing how mistaken they
are in assuming that these are the actual, original versions of matter
existing in the "external world." They are misled, because by means
of our senses, we can never reach the matter itself.
Again, our brain interprets and attributes meanings to the signals
related to the "external world" of which people imagine they are in
contact with the original that exists outside. Consider the sense of
hearing, for example. In fact, our brain interprets and transforms
sound waves reaching our ear into symphonies. That is to say, we
know music as interpreted by our brain, not the original music that
exists outside. In the same manner, when we see colors, different
wavelengths of light are all that reaches our eyes, and our brain
transforms these wavelengths into colors. The colors in the "external
world" are unknown to us. We can never have direct experience
of the true red of an apple, the true blue of the sky or the true green
of trees. The external world depends entirely on the perceiver.
Even the slightest defect in the eye's retina can cause color blindness.
Some people perceive blue as green, others red as blue, and
still others see all colors as different tones of gray. At this point, it no
longer matters whether the outside object is colored or not.
The World of Senses Can Occur Without Outside
World's Existence
One factor which reveals that everything we see and experience
exists in our brain and that we can never know the original of the
matter that exists outside is that we do not need an outside world
for senses to occur in the brain. Many technological developments
such as simulators and also dreams are the most important evidences
of this truth.
