Even if 10 times is an exaggeration, I think it's about 3 times more blissful, and also, the quality of bliss itself seems different.

Even before, for example, when the aura was mainly in the manipura (solar plexus area), I felt energetic and had a certain sense of happiness. But in the next stage, when the aura was mainly in the anahata (heart chakra), I felt a lot of happiness, and I suppose it could be considered a kind of blissful experience.

Next, when the aura flowed to the ajna (third eye) for the first time, I felt a certain sense of peace and happiness, and I was quite satisfied.

After that, I gradually merged with what is called the higher self (or guide), which is felt as a mixture of three consciousnesses: creation, destruction, and preservation, and that was also blissful. However, it was a state where the eternity of those three consciousnesses, as a collective, was strongly felt.

Then, the higher self's aura, as if mixed with the kundalini, or the kundalini close to the physical body along the spine, started to rise again, reaching the ajna (third eye), and I think that further purified the body.

Only recently, after reaching that point, the sahasrara chakra has started to open, and it's not completely open yet, but about 20% or unstable. However, even in that state, I think there's about a 3 times difference compared to the bliss and peace I felt before.

Once you've experienced this bliss, it's impossible to go back to the previous state. And suddenly, when I think back to the many, perhaps dozens of times, of what are called past life memories (although not all of them are necessarily direct past lives), I feel that if I had known this state, I would have had a completely different life, and I feel that I've been wasting my time.

At the same time, I feel (a little) that I want to somehow save the lives of others who are living difficult lives, being tossed around by the waves of the world, without knowing this sahasrara.

Well, saying "save" is presumptuous, but it's just a personal feeling.

I, too, have lived many lives, and even without knowing this, I was still a spiritual person or lived a normal life. So, before I say anything to others, I should first consider my own past. But when I look back at my past lives, I feel that I lived a very wasteful life, a life without knowing the truth, a life without knowing the light and guidance of the sahasrara, and I feel quite regretful (although it's not a negative feeling).

Taking that into consideration, I still feel that I have a lot of room to grow, but I've started to think that if the opportunity arises, I might be open to taking on a disciple. However, I don't expect many people to want to be my disciple, and until now, I haven't had any intention of taking on disciples, nor have I intended to be in a position of being a teacher. It's just that I've started to feel that I might want to try it, to a small extent.
