If the Sahasrara at the crown of the head is not open, the energy does not flow properly, and it can feel a bit stiff. Recently, it has often recovered quickly just by doing regular meditation. However, even on days when it is difficult to open and feels stiff, I think that by doing a "mushin" (no-mind) meditation, it is possible to gradually open the Sahasrara at the crown of the head.

The term "forceful" may be misleading, but I use very little physical strength. I simply focus my awareness. By focusing my awareness on the stiff area at the crown of the head and directing energy there, after a while, something seems to break down, and it suddenly loosens, allowing energy to flow. By repeating this process gradually, the flow of energy improves and it becomes more relaxed. Sometimes, it loosens in stages, such as 5 or 10 stages.

If there are any distracting thoughts at that time, it is difficult to loosen, and I think this is probably because energy is being used by those thoughts and distractions. To focus only on the energy that loosens, it seems to loosen quite quickly if you become "mushin." In other words, you direct energy in a "mushin" state to the stiff area. Rather than a specific area, the stiffness is on the outside of where the energy is not flowing, like the outside of a balloon that has been deflated. So, I focus my awareness (in a "mushin" state) on the boundary between the relaxed area and the stiff area.

You may wonder what it means to "focus awareness" while being "mushin." It means stopping the logical mind that thinks and directing only the underlying will and awareness to that place, concentrating on it. By focusing awareness in a "mushin" state, a considerable amount of energy gathers there, and that energy forcibly loosens that area.

The term "forceful" may be inappropriate as an expression, but because a considerable amount of energy gathers, although there is no physical force applied, the effect is often like something that has been "forcefully" opened. This is not because I am actively applying force; although focusing awareness is somewhat active, I am not applying force, but simply directing awareness, stopping the thinking mind and focusing only awareness on the stiff area at the boundary.

By keeping the mind "mushin" and simply providing awareness, without using any physical strength, a considerable amount of energy is directed to that area, and eventually, as a "result," an effect that loosens somewhat "forcefully" is created.

You might wonder why it's called "rikizuku" (forceful) even though you're not exerting force. The truth is, the "effect" is as if it's "rikizuku" because it's achieved by focusing your consciousness.

In this way, energy flows well into the relaxed areas, and in yoga, this is called the "nadi," which is an energy channel. This nadi gradually opens (relaxes) each area, from the middle of the head (as Ajna) to the frontal lobe and then the top of the head. With each step, the consciousness deepens its relaxation, the energy increases, and the clarity of awareness also becomes sharper.

This is quite a basic concept in meditation these days.

Effects:
- Relaxation
- Increased energy, a feeling of fullness (a feeling of fullness that goes beyond emotional bliss)
- Clarity of consciousness
