How can a bright and colorful image appear in your dark brain?

		In the Darkness of Our Brains We See a Bright World

There is another point that should not be neglected; light cannot pass through the skull. The physical area in which the brain is located is completely dark, and light cannot possibly penetrate it. However, incredible as it may seem, it is possible to observe a bright and colorful world in this total darkness. Colorful natural beauty, bright sights, all the tones of the color green, the colors of fruits, the designs of flowers, the brightness of the sun, people walking on a busy road, fast cars in traffic, clothes in a shopping mall—are all created in the dark brain.

Imagine a barbecue burning in front of you. You can sit and watch the fire for a long time, but throughout this entire time, your brain never deals with the original of light, brightness or heat from the fire. Even when you feel its heat and see its light, the inside of your brain remains dark and maintains a constant temperature. It is a profound mystery that, in the darkness, the electrical signals turn into colorful, bright visions. Anyone who thinks deeply will be amazed by this wondrous occurrence.
