筋道不舒長,欲伸而筋不能伸*
When the fascias channels are constrained and short, one cannot stretch at will
手屈而不伸者,其病在筋**
He whose hands are bent and not extending, its illness is in the fascias
To furthermore understand what is sought for in the search of straightness, and even elasticity more generally, it may be interesting to explain furthermore the first quote, from the Fascias Change Canons, more known as the YìJīn Jīng. Indeed, it contains a few keys to understand what is sought for when working with fascias. As it has been mentioned in a previous post, martial enigmas always hold more than one meaning (hence, the above translation of the first quote was meant to illustrate a former post). Then, from a basic understanding, one can try to expand certain characters.
