This morning, the area from the base of the skull upwards, towards the back of the Sahasrara on the crown of the head, began to loosen significantly. On the same day, the upper part of the forehead also began to loosen.
This area, like the previous time, started at the back of the head and gradually moved forward, with the loosening progressing overall. This time, it seems to be starting at the back of the head again and progressing forward in stages.
Although it is not completely loosened overall, the loosening is deepening gradually, and along with that, the energy passing through the Sahasrara on the crown of the head seems to be increasing.
The upper part of the forehead, and also the area slightly behind the forehead, are also beginning to loosen. It feels like it will take more time, but it is steadily loosening.
Sometimes, the area that loosens changes with each meditation, such as the forehead, the back of the head, the back of the crown, and the front of the crown, and the loosening deepens little by little.
Sometimes, if I do too much suddenly, I feel dizzy or experience slight tingling sensations, so I am observing and proceeding cautiously, and meditating within a comfortable range to loosen the head.
