Thousands of years ago, the ancient Greek philosopher Plato already posited that there is a gentle glow within the human body, a flame that exists in our eyes, but its nature is not combustion, but rather designed by the Creator.

Nowadays, with the continuous understanding of human vision, this kind of light has been given a scientific definition, namely, photopsia.

Why can humans see?

Firstly, after entering the eyeball, external light is refracted by the lens and ultimately forms an image on the retina. On this basis, the retina is composed of millions of photoreceptor cells. Upon receiving light signals from the outside world, these cells convert them into electrical signals, which are then transmitted by nerves to the visual center of the brain. After the brain processes this information, we are able to see external images.

Why can we see light even with our eyes closed?

Although external light cannot reach the eyeball after the eyes are closed, the human body may release extremely small amounts of photons during some normal metabolic processes and biochemical reactions. For example, the respiratory process in mitochondria, lipid peroxidation, peroxisome-related reactions, etc.
Meanwhile, these photons have different wavelengths. When photons with visible light wavelengths exceed a certain threshold, they may trigger the perception of photoreceptor cells, which then transmit signals to the brain, allowing you to see the image formed by these photons, that is, the colors and ripples you see when your eyes are closed.

From Bible:

Many, LORD , are asking, “Who will bring us prosperity?” Let the light of your face shine on us.
( Psalm 4:6 NIV )

Let your face shine on your servant; save me in your unfailing love.
( Psalm 31:16 NIV )

When praying, ask God for illumination. Of course, you should close eyes, when you pray.

In China, for Buddhism and Taoism people, seeing white light filling the room during meditation is a basic goal.

My explaination for the light.

After we enter certain state of quietness, we can see the light which can show the spiritual energy strength. Before enter the quietness state, we can see light spots and stripes. It means you still do not close your perception system, you should stop your eyes, ears, nose, tongue, body, and mind, which can give you information from your body outside. when these parts of your body stopped, some part will begin to work. I mean “conarium”, it will perceive our spiritual energy. The brighter you see the light, the higher your spiritual energy. When you see the light filling the room during meditation, you enter the the world of mysticism.

The perceptual ability of the conarium and the higher spiritual energy is our target to improve. There are many legends about a group of people in the world who can predict the future, and there are also some incredible prophecies left in the world. I cannot get the ability yet, but i know i will be able to obtain it.

In the next article, I will explain how to enter the world of mysticism through meditation.
