Recently, my challenge has been to fully and completely open the Sahasrara chakra. Previously, I would only focus my awareness on the ajna (third eye), Sahasrara, or the back of the head during seated meditation, and relax those areas. However, recently, in addition to that, I've been consciously focusing on the Sahasrara at the crown of my head on a fairly regular basis, even in my relaxed daily life, and gradually relaxing it.

While working, there are often many things to think about, so it's not always easy. However, when I'm doing work that allows me to relax, or when I'm cycling or walking in my daily life, I try to focus my awareness on the crown of my head and gradually relax the Sahasrara.

I know that seated meditation is more efficient, but I spend more time in my daily life, so the effects are gradually appearing. I can feel my crown tingling and a slight loosening sensation, often accompanied by a "gori" feeling. I think this will take time, so I think it would be better if I could do it constantly.

In addition to that, I've recently started to feel a strong effect from the Khechari Mudra. Although I say I've started to feel a strong effect, it wasn't that intense at first. However, gradually, I've become accustomed to extending my tongue for about a month, and I've realized that the effect is higher when I direct my tongue firmly towards the area I want to relax. So, I've been experimenting with different directions, pointing my tongue upwards or towards the back of my head. In reality, the Khechari Mudra taught in yoga usually has a fairly fixed placement for the tongue, and it's not common to change the direction like this. However, the effect of the tongue's direction on how easily the area relaxes is absolute, so even though I haven't been taught by anyone, I'm using a highly effective method. Initially, I only did this during meditation, but now, in my daily life, if there's an area I want to relax, I keep my tongue pointed in that direction, and the awareness and the direction of my tongue cause the targeted area to gradually relax, making a "piki-piki" sound and a "boki" sensation, becoming softer. Then, once one area relaxes, another area becomes slightly tense, so I focus my awareness and tongue on that tense area and further relax it.

Not long ago, it took a considerable amount of time to relax even once, and I would often feel satisfied and end the meditation after just one level of relaxation. However, now, it's not just once, but dozens of times, and perhaps even more times that I can't even remember, with a "piki-piki" sound and relaxation. Even after relaxing, it becomes slightly stiff again after a while, so I'm trying to relax it even more to keep up with the speed at which it stiffens.

Ultimately, the goal is to open the Sahasrara chakra completely, just like the Vishuddha chakra has changed, so that there are no energetic blockages at all, or to reach a state where it is partially open and then opens automatically.

Looking back, I think that if I had known these things (tips and principles), the Vishuddha chakra might have opened sooner. But, well, that's because I didn't know it at the time, so there's nothing I can do about it.
