The aura has not reached the inside of the head very well until now, and even when trying to let the aura pass through, it was difficult. However, recently, I have succeeded to some extent in condensing the aura, which surrounds the center of the head like a hat, from all directions into the center of the head, focusing on the area around the eyes, the top of the head, and the back of the head.
However, this is only the beginning of the aura reaching the center, and the center of the head has not yet completely relaxed and started moving. At least, the "stronger aura" that previously only slightly penetrated the area around the eyes or eavesdropping has now started to penetrate towards the center of the head.
It doesn't feel like the stronger aura has reached the very center of the center of the head, but at least, while the "stronger aura" used to move in the relatively superficial parts of the head, it now feels like it has started to penetrate towards the center, reaching about half to two-thirds of the way.
As a result of this, the center of the head has become more relaxed, and the feeling of a machine that was stiff and creaky has become slightly smoother, as if oil has penetrated. Although it is not completely smooth yet, it feels like the "stronger aura," like oil, has finally started to reach a little bit towards the center.
