Those with “sensitivity”, wouldn’t they be the ones that can yield or absorb this kind of force to their advantage or just neutralize it so nothing happens rather than being tossed around ?
Good observation
Think of a bell that is struck by the clapper inside. Depending on the bell, the sound it makes can vary greatly, and in some cases, it might not produce much sound at all. The difference in sound is primarily due to the materials and shape of the bell.
The same could be said of the clapper, the object that strikes the bell. It is also affected by its material and shape.
We can refer to these components (the bell and the clapper) as "media."
The medium in this case is not the body directly, as pointed out in various theories. Instead, it is a field of energy thought to surround and be connected to the body, referred to as '气场' (qì chǎng) or 'field of qi.'
Looking at it through this lens can account for many of the phenomena and reactions people experience with practices based on this concept.
As all of the teacher's listed in this post, expressed the same theory in different ways.
For most people, their qi can be described as '散气' (sàn qì), meaning qi that is not harmonized within the body. Consequently, their '气场' (qì chǎng) may be quite small.
This means that the teacher may need to allow the student to borrow their qi, by being able to project it. The practice of doing this referred to as "
凌空勁 Volley jin"
This what is being reacted with, depending on theory followed.
Teachers with high levels of skill are often reluctant to do this with outsiders, for fear of damaging them...
It's a lose , lose situation.
Once asked my teacher about this.
he said " if they are not sensitive to it, and I use to much, they may be damaged in such a way I can not help them.
If I don't use enough they will feel nothing. For those who have built up a good level of "qi" within them through MA practice or other means. They often are sensitive to it, and will react based on this sensitivity.
The concept is similar to how a judo player borrows the opponent's center of gravity to execute a throw, facilitating movements and techniques that might otherwise be difficult
