Meditation is the concentration on this aim. This weakens other aims - neural networks - according to the laws of midpoint mechanics.
The same goes for the relaxation.
The central point is letting go. The essential point is to perceive the urgent thoughts and feelings, but not to respond to them. It does not give them the space or attention they need to evolve.
There is a theory that seems very plausible to me: The state of meditation arises through brain processes. It begins with the goal to eliminate all thoughts, feelings and perceptions. So, it is very important to stop the constant chatter of thoughts. The concentration on it produces active neuronal activity in the attention midpoints of the brain. This signals to slow down the inflow of neuronal information. As a result, an area that is responsible for our orientation in space is increasingly being cut off from neural impulses. If the area lacks the necessary stimuli, it only remains for him to create the subjective impression of complete spacelessness, which is interpreted as infinite space and eternity. Another area is responsible for the idea of the limitations of our body. The total failure of signals on this page means that the perception of itself becomes limitless. As the depth of meditation deepens, the boundary between the inner and outer world blurs and a feeling of expansion and merging with the environment begins to emerge. By concentrating on one point, the flood of information, from which man derives his orientation, disappears. As a result, the boundary between the self and the world vanishes, the sense of oneness with the world and the limitlessness sets in. In the deepest meditation you have the feeling of becoming one with the universe, dissolving into something much bigger.
This could be illustrated by the example of falling asleep: often a thought comes to you that you do not want to think about (anymore). If you look at it, then you are at the midpoints of this particular goal, which wants to occupy you. This is especially the case when fighting against the thoughts. But if you do not do it, but return to your goal of falling asleep, your thoughts will lose value.
This would be a way to ward off compelling thoughts: not to focus on them and to focus attention or awareness on the midpoints, such as meditation.
Relaxation means that other goals are no longer effective (other goals than those in which you are at the moment, such as relaxation, meditation).
The more often you practice this, the better it works.
My meditation (relaxation) exercise is that as I breathe in, I want to get closer and closer to the end of the universe, and when exhaling, I'm just below that limit I've just reached.
What is very important: There should be no free space between the "end of the universe" and this border that I have just reached.
Note: Since the universe is infinite, of course, I can never reach the end of the universe. And so, I can continue this exercise indefinitely.
For achieving inner peace, two conditions are particularly helpful:
