I have been continuing meditation that allows energy to flow through each part of the head. As a result, blockages in each area are being released, and movement is appearing. Recently, I have been focusing particularly on relaxing the area around the forehead, but not only in that area, but also in other areas, I feel that the relaxation has deepened.

The relaxation is deepening from the back of the head to the Sahasrara chakra.
The relaxation is also deepening in the crown area.
In the center of the head, the relaxation is deepening, and movement is appearing, accompanied by a sensation of a slight shift or a feeling of something collapsing, or sometimes, vibrations spread out like ripples as the relaxation occurs.

As a result, the movement in the center of the head becomes more active, and while there may be some physical movement, something energetic builds up above that, creating a pressure-like sensation, which can sometimes feel a bit constricting.

Then, while there is movement in the center of the head and the pressure is increasing outwards, suddenly, a similar sensation of a slight vibration and a feeling of something collapsing occurs in the back of the nose, and it feels like the nose moves forward slightly. As a result, the pressure in the center of the head is slightly released and becomes more relaxed, and the feeling of constriction is alleviated.

I feel that this process of initially alleviating the constriction, and then, as the energy in the center of the head increases and movement appears, the constriction returns in a different part of the head, which then relaxes again and movement appears, is repeated.

It seems that I have been repeating this process for quite some time. I am increasing the energy, using pressure and movement to relax each part of the head, and as a result, I am gradually improving the flow of energy and further increasing the energy, repeating this process many times, albeit very slowly.

Now, the head seems to be somewhat relaxed, but it is not completely relaxed, so I am continuing to do energy work diligently.
