Recently, Rudra Granthi has begun to dissolve, and I have finally reached the entrance to the second stage. I feel that this is where the state truly worthy of being called Samadhi begins.

I have had moments before where I thought, "Is this Samadhi?" but now, it seems that the Samadhi I experienced before required effort, while the Samadhi I am experiencing now is a Samadhi that does not require effort, although it is still weak. It can be said that the state where effort is not required is gradually becoming stronger.

It is said that there are Samadhis that require effort and Samadhis that do not require effort. The former is a transitional state, while the latter is true Samadhi. If this true Samadhi corresponds to the stage where Rudra Granthi dissolves, it makes perfect sense. If it is said that Samadhi requires effort before Rudra Granthi dissolves, is in an intermediate state during the beginning of Rudra Granthi dissolving, and becomes a Samadhi that does not require effort after it dissolves, then the yoga system is very well organized.

Before Rudra Granthi dissolves, Samadhi is an "action," but after it dissolves, it becomes a state of "inaction" and "normalcy." This is because, in the former case, the state of Samadhi is maintained only by suppressing thoughts with effort, while in the latter case, it is not necessary to make any effort.

However, this is not a complete switch that happens in an instant, but rather a gradual change. Gradually, the need for effort decreases, and gradually, Samadhi becomes possible with just a little effort. Then, at the stage where Rudra Granthi dissolves, the balance shifts, and what was previously the dominant aspect requiring effort becomes the dominant aspect that does not require effort.

In my case, I have just passed the peak, so even though it is said that it does not require effort, I still feel that I deepen my Samadhi a little by making a little effort. However, the basic principle is that it does not require effort, so it is not a big problem. However, I feel that I deepen the state of Samadhi with stillness and observation by concentrating just a little.

At this stage, the movements of the limbs become more clearly felt, and the vision becomes more detailed and clear. It can be said to be a kind of Vipassana, or perhaps it can be said to be Kanika Samadhi. Previously, both Vipassana and Kanika Samadhi were supported by some effort and will, but now, it automatically enters a state of such subtle observation.

I think that before entering the Samadhi state, I wasn't truly living in this world.

Perhaps there are people who are born with this state, and others who are not, and while everyone thinks their perception is the same as others, the reality is that it's quite different. There are people who live in a Samadhi state without even realizing it, while others don't, and I think there are many people who live in Samadhi without even needing to practice. In fact, people who are practicing might develop an inflated ego, which can be troublesome, so I think it's better to achieve Samadhi in ordinary life.

Once you reach Samadhi, it turns out to be nothing more than simply living in this world. It's not something special, it's quite ordinary. I wonder if there are surprisingly many people who can't do this ordinary thing.

...And the next morning. While dozing before waking up, suddenly, there was a "click" in my head, and the upper half of my head relaxed further. This "click" has been happening almost every day for the past six months, but it progressed further this time. It clicked again, and it relaxed even more, and when I meditated after waking up, the relaxation was more advanced than the day before. It's a cycle of relaxing and tightening, but it's been going very well for the past few days.

However, it's not completely relaxed yet, but it's become a little easier to enter the Samadhi state compared to last night, so I think it's stabilized somewhat. Even yesterday, I was naturally in Samadhi without any effort, but this morning, it seems to be even more effortless and stable.

When I meditate, I still hear "tick-tick" and "crack" sounds in the center of my head, so it seems that it's not yet in a complete state. I'll continue meditating further.
