Recently, the ego has been absorbed by the higher self, and as a result, the higher self itself has begun to think consciously. I think that the relationship between the higher self and the ego is like the difference between someone who makes noise in a library or a quiet cafe, and someone who wants to be quiet.
We experience these kinds of things in the physical, three-dimensional space of reality, but the same thing is happening invisibly within people.
In a normal, quiet cafe, the person who is making noise is probably having fun, but the person who wants to be quiet in the cafe is thinking, "It's so noisy. It's annoying."
The same thing seems to be happening in the relationship between the ego and the higher self within a person.
When the ego is making noise within a person, the higher self says, "It's a little noisy. Please be quiet." Then, the ego becomes aware of its own noisiness and thinks, "Ah, I was a little embarrassed," and becomes quiet.
This relationship seems to have a similar relationship to the physical space.
I remember that when I was younger, I used to think that I "prefer to be quiet," and I would think, "That person has no manners" when someone was not being quiet in a place where they should be quiet. However, when I re-examined the noise of the ego that is happening in my head, I realized that although there is a difference between physical sounds and thoughts, in essence, it may not be that different. With a little embarrassment, I feel a deepening sense of self-control.
Of course, there is a difference between the physical and the thought, but I think that true peace or true silence includes thoughts as well. So, even if you are quiet physically, if your thoughts don't follow suit, it may still require further effort.
It is often said in spiritual circles that humans on Earth have a lot of mental noise and distractions, while aliens only think when necessary and communicate telepathically. However, if we cannot completely control our thoughts, even aliens may think, "This human is noisy," and be bothered by it. Since communication in the universe is mostly telepathic, even if you can be quiet physically, if you cannot be quiet in your thoughts, you are still not considered fully mature. In order to achieve that, the ego needs to be subdued, and the higher self needs to be in control of thinking.
