The Mechanism Of The Creation Some Questions from My Fellow Brothers and the Answers
It is well-known that races with almond-shaped eyes think that other races' eyes are crooked, and their eyes are the correct shape.

My dear brother, I received your letter, and we thank you for your kindness. Even though the discussion on colors is very lengthy and requires a separate book, However, I will answer it not to leave any letter unanswered:
Black color does not exist, and these are names created by humankind because their eyes see it that way. The reason for this is that the entire universe is light, and there is no darkness. There are no such colors as black or white or yellow or blue for the spirit's principles and regulations, not the way it is in our world because, in the infinite universe, everything is light. With the light from the sun and colorful rays of light, this space that we see are specific characteristics of this physical body and this planet of ours.
Every humankind's eyesight is different according to his body mechanism and, every person perceives the color black or blue or red in a particular manner distinct from others. People who have Daltonism (Protanopia, a form of color blindness) perceive colors differently from others. For instance, what others perceive as red, they may consider green, and so on. However, we should not forget that a person diagnosed with Daltonism sees the colors correctly in his world, and if people tell him otherwise, he is not going to accept them. People consider individuals with such ailments as "deviated from the natural state" because most people see colors differently. Hence, they conclude that he sees wrong, while he thinks that others see wrong. In other words, both consider themselves right in their beliefs. As another example, races with almond-shaped eyes think that other races' eyes are crooked, and their eyes are the correct shape.

Even ordinary people do not perceive colors with the same intensities. For instance, the way you see the color blue is not the same as I see it, and everyone may perceive it differently (with the slightest of difference). The same principle applies to the color black. For instance, when a draper holds a black cloth over his hand, one may see it as pure black, while another may see it black-brown, and another as gray. It is on a rare occasion where two individuals see a color identically. None of these people are lying because this is what their eyes perceive. If black is an absolute color, then how come it is perceived differently?
The reason people are different in perceiving colors is the difference in the number of elements and chemical mixtures of their bodies. Which is different in each individual, and some have less of a particular element, and some have more. By consuming specific seasonings and adding elements to the body, the human's eyesight power alters. For example, you may see a piece of paper as entirely white, while another sees it as shiny white, and another sees it mixed with yellow. The third person who saw the paper as yellow, after consuming Vitamin A the next day, may see it as entirely white. All these differences arise from differences in the mixture of elements.
To prove color is not real, and it is a human perception, we give the following notion. When a person has a fever or is unwell, he may hallucinate colors or see colors more intense or subdued. When you are using anti-parasite medicine (a specific drug that contains Santonin), you will see any brightness as the color green, because the drug is in your system. What is this color? Your eyes are the same, and the person is the same; so how come the color is different? Is it an external reality? Of course not. This difference in perception of colors is due to the change in the body's chemical elements that emerged by adding the drug to the body. Therefore, you perceive additional colors.
The rays of sunlight contain many color combinations that one can easily see through a prism with naked eyes. These rays will be seen as white (a mixture of all colors) if they have no collisions (frictions) along the way. However, if there are obstacles along the way, like clouds or drops of rain, those obstacles and objects will create a characteristic of "reaction" resulting from these collisions. The rainbow can be seen in the sky when the sunlight collides with water droplets. It is the sunlight's reaction, not the ray itself.

The rainbow can be seen in the sky when the sunlight collides with water droplets; it is the sunlight's reaction, not the ray itself.

At nights, when the sun is hiding behind the earth, those rainbows and their colors still exist, but we see them as black, simply because at night, there is no direct sunlight to help us see them. Therefore, due to the lack of light, we see black, which is a shadow, not a color.
The reason for seeing colors: when the sunlight (which is a mixture of all colors) shines over an object, that object passes all colors except for its own specific color. Therefore, we only see that one color. In other words, the reason for seeing a specific color is the lack of that color and the fact that the object cannot pass that particular color. So, we imagine an adverse action as a positive result of color. At night, when there is no light, objects cannot pass any lights, and thus, we see everything as black; while this black is not real, it is just a shadow. Consequently, seeing red is, in fact, "no-red" or its reaction, and seeing black is "lack of colors or no-colors." As already mentioned, this black is manifested differently in every human’s eyesight.
The angle each person perceives colors is different. From every angle that an individual's eyes focus on, an object's color will be perceived either with more intensity or more subdued. Now I will ask: how come if it is the same color, a different angle of view (like passing the light through a crystal) alters the eyesight's capabilities?
To clarify, consider a clear drinking glass placed upside down on a table.
When the light shines over the glass, it demonstrates the color white or a combination of all lights. Now, put a red object over the glass. The color of that object will reflect into the glass, and we see a red image of that object inside the glass. However, this image is not real, and we cannot obtain that red object from inside the glass even if we break it into pieces. We cannot reach that red object that is being projected. This notion is because the image is merely a reflection we see, while our eyes consider it a real thing and perceive it as a real object; otherwise, we would not have seen the image at all.
When we put that red object over the glass, in actuality, we block the red ray in which the white ray was shining over it, and we see a red image inside the glass due to the lack of the red light, not that the image inside is red in reality. We see these colors in different tones and intensities from different angles and perspectives. The reason for that is what obstructs the light, whether a lot or very little, the color will lose its intensity until no color is visible at night. When there is a low level of light from the moon or other source at night, we perceive weak intensity rays of the color of objects.
There are various colors with different intensities in space, which are multiplicities and together establish a Unity of colors. In that glass example, any object with any color we put on the top of the glass will project inside it, even though there is no color inside that clear glass in reality. We see this color and reflection when the white light shines on it; all colors will pass through except for the object's specific color. In other words, when we see color, it is due to what has obstructed us from seeing that color, which is the object here.  If we take the object away, and it is only the transparent glass, all colors exist, but the glass does not show any of them since there are no obstacles along its way. If you put a green object, you will see green, and if you put a multi-colored object, you will see all of them because the object will barricade all those colors.
For these reasons, we can say that we see a specific color because that color does not exist.
If we put a black object before the light, we see black color because it has obstructed all colors. Black has no reflection; it prevents the reflections of other colors. Therefore, we perceive it as black due to the lack of colors. An old saying Persian proverb denotes that "there is no color beyond black color."
When the lights illuminate, human sees nothing but a light that is the accumulation of all colors. This accumulation of colors is the meaning of "Unity." Wherever a color is seen that specific color has obstructed that same color with the manner described above.
Suppose we mix different colors with specific ratios and do not miss anything while adhering to the process's chemical principles; the resulting color will be black that bars all colors when placed in front of the light. If the Tricolor ink (including the three primary colors, namely red, yellow, and blue) in the printing agencies is printed over each other, the result will be black.
To elaborate on the tricolor ink, let me clarify a little: if you put a red object on our crystal glass, you will see the red reflection inside. If you add a yellow object, you will see an orange reflection. Finally, if you add a blue object, the reflection you will see inside the glass will be black.
To summarize, a red object obstructs the red light, and we see that object in red (in other words, we perceive an adverse action that stops the light as a positive action). Because black stops all colors, we perceive it as black, which is a mixture of all colors. The essence of colors is the light itself, and in the existence of light, darkness does not exist at all.
Now to answer your second question: My dear brother, I am most certainly against using such complicated and perplexing words and writings that only a few understand. I believe that notions should be written in such a way so everyone can understand easily, not phrases and expressions that nobody understands. Besides, I have provided an answer to this question in this book on pages 142 to 172, in the answers I provided for the questions by Mr. Maleki Moayyeri, the Chemist at Azerbaijan Textile Co. Regardless, I am going to provide a brief explanation to answer your question in the following.
We could describe "existence" as the fundamental essence of the universe's elements, including all creatures. The purpose of nature is the evolutions, forms, and transformation of the elements' essence, just like the many shapes created with beeswax. The beeswax itself can be perceived as the essence's elements or the genuine existence, while the forms it is shaped into are nature and its affiliated affairs.
Using such terms, copying the old philosophers to entertain themselves is nothing but futile terminologies. The truth is what is provided on page 159, and you are going to understand everything clearly, if you ponder deeply on these notions. As already mentioned, the spirit is not parts by parts and individualized. However, it is a broad and universal spirit that functions with all the universe's creation. Everyone utilizes it according to its level of mechanism and container capacity.
Finally, we are very thankful for all your questions and are always prepared to answer questions from our friends and fellow brothers and sisters. You have a place in our hearts, and we wish prosperity and felicity for all of you from the almighty. We hope that all our fellow brothers and sisters strive and have the highest aspiration towards Unity's goal.
