The following example can generate a shadow projection of the basic ry, and there is another piece of code that cannot be projected. It is similar to the code that can be projected with this copy, but it is always impossible to do so, further verification is required to know where the specific differences are and which key parts play the role of shadow.

Let's just calm down and clarify every line of code. This is a shortcut!

The result of the pursuit of shortcuts is to blindly touch the image. In the end, the more you touch the image, the more you get out of the way. Even the original unconscious world is gone.

Therefore, Buddha warned us to pursue the truth, just like a child.

In fact, it is to remove the delusion and speculation, and realistically consider the problem based on the original face of the matter, so that nothing can be guessed by the terminal will affect your mood, and even deviate from the normal path, give birth to events.

A piece of information circulating in this article probably means that if you think about it, you will do it without knowing it. After doing so, it will produce results. After the effect lasts for a long time, it will become a habit, when you get used to it more often, you will become a character, and character determines fate.

Therefore, to change, first change your mind.

This is not an idealistic theory. Sometimes it is true that pure materialism often allows people to ignore and change their thinking and subconscious to the material world.

The most basic difference between humans and animals is that humans can change the state of their own world through thinking. Of course, this state is also one of the various choices inherent in the material world, but at least it can be selected.

If we do not control it, it will become a random choice. The physical world may be in good or bad state, and the random choice results can be imagined. It is completely bad or not.

To sum up, the advanced level of human beings lies in the fact that, by thinking and guiding actions, the default options can be changed and favorable options can be prioritized.
