Generally speaking, Qigong only talks about Sundays, but actually it just peeks into a small corner of the avenue. According to the Taoist scriptures, there are three realms on the basis of Sunday: out-of-body experience, manifestation, and ghosts and gods. Please let me come with you.
Sunday is the base camp of Qigong. What's the use of surviving Sunday? I don't know if you have heard of it. Getting through big and small Sundays is actually an effect of practicing Dan. You can get through the meridians with your own essence, such as getting through small Sundays and letting qi pass through the du meridian, from chest to hip, from hip to top of your head, and from top of your head to navel. In this process, Qi just draws a circle in the body, that is, Inner Dan, to get through the small Sunday, get through the small, and get through the big. Mainly to nourish the five internal organs and strengthen a person's soul. In traditional Chinese medicine, a person's soul is directly related to the five internal organs of the human body. When the five internal organs are strong, a person's soul will unite and lay a solid foundation for his OBE. Therefore, Taoism calls this process "building the foundation".
Out-of-body experience means that when your soul reaches a certain level, you can try to get out-of-body experience, just like the average person's soul is as weak as a baby, but by laying the foundation on Sunday, the baby can grow up and swim in the water. At this time, you can imagine yourself standing under a building, going up step by step, and jumping off at the top of the building. You should go back immediately after your OBE, because you were too weak at first and didn't go back for five to ten minutes, so you never want to go back.
After a long time, the out-of-body experience will be long. At this time, try to get out-of-body experience at night. At this time, we usually call it a "night tour". After a long time, the soul will get out-of-body experience in the morning or at night. At this time, it is also called "one-day tour", which is the highest state of out-of-body experience. But in this state, the soul is invisible, can't get anything, can only be in it. You can confuse people with a little magic. The so-called "enclosure" that people often say is these things. These tricks can only confuse some weak people. When you meet a strong person, just like snow meets the sun, you can't get close. There is nothing he can do.
The next realm is "Emperor Manifestation". I doubt very much whether the old man you mentioned has reached that level. At this time, his spirit has grown to a certain intensity, and he can barely pick up some light objects. The realm at this time is called "Emperor Manifestation". If his spirit continues to be strong, he can show it through things, usually with the help of some clear spells or then.
The old man you are talking about is about this realm. He can knock out objects out of thin air. Although it sounds easy, in fact, Master and I have never seen anyone cultivate to this level in these years, let alone ghosts and gods. I guess it's just something in the book. I heard it occasionally today. I wonder if you can tell me the name of that column and let me have a look. I hope this is not a lie. ...
