The yogi requires that the light between the eyebrows is not transparent, that there is black silk in a circle of light and red light outside the white aperture. What is the phenomenon?

Don't be too fascinated! It's all natural phenomena, it's no big deal! You can see all kinds of light in front of you, but it is actually the light of all kinds of internal organs in your body. When you are calm, you will leave on Sunday! Come to your eyes, you will see all kinds of light, nothing magical! Light means that the yang is sufficient, light and shade means that the internal qi is insufficient (bad spirit), and a piece of black means that the body is in a general (sub-health) state!
