Did you know that Tai Chi is circular and spiraling on the outside, and at the same time twining on the inside? If done correctly you?
will create the internal explosive fajin power in all your strikes. If you apply the Tai Chi principles to every move, then you will feel the subtle twining inside the body necessary for creating fajin.
The subtle feeling of wringing out a wet towel in every movement is "twining" effect. Performing Tai Chi correctly will open up any blocked chi channels and is healthy for the internal organs.
