Kai-lei movement
In order to understand how the kai-lei movement works you have to know how humans have an energy within that is very powerful and is not easily available and that also the human brain cannot control it if it is accessed beyond its own level of control. If this occurs then a shaking nerve response occurs which is seen so the level accessed has to be reduced.
There are 12 levels in all and within each level there are 12 aspects each with its own energy level so there are many to work with.
Training is done via both mental exercise which comes first and then the movements themselves with the energy active.
