They are out of their minds, allow their bodies to be dominated by the Paraconsciousness or external messages, and exhibit some strange behavior. Such a person will jump out of a building or into the water if he is told to do so. He himself does not even want to live, and he gives up his body to others. That does not belong to cultivation insanity but to going astray while practising qigong. This is caused by an intentional pursuit of such a state at the beginning.
Many people think that wobbling their bodies unconsciously is a practice of qigong.
In fact, such a state will lead to serious consequences if really carried out. It is not the practice of qigong, but it is caused by ordinary people's attachments and desires. They can not put all the blames squarely on Falun Gong when something is going wrong after they fail to discipline themselves in line with Falun Gong's requirements. To illustrate this by an analogy, working in a factory is prone to accidents, perhaps fatal ones, if one can not closely follow the procedural instructions in his work. This is not a problem for the work itself, but only for the careless worker.
