When you travel through the different martial arts and healing arts (methods), and start to see a common thread through all arts, methods and systems of which is, that of the hu~man perspective of actually taking part in the said art, method or system,
It soon becomes apparent that the common thread principle does not only apply to arts, methods and systems that you have been exposed too, it has a greater meaning and perspective, that of all manner of thought produced materiality (any subject on or off the planet conceived and believed to be achieved) also all natural occurrences, have one thing in common, that is the thread that binds them all,
i.e. human participation in order to have a derivative from the said experience/ manifestation whether man made or nature born.
The topic could be history (what about her story), politics (many bloodsuckers) sports, or any topic from stamp collecting to the meaning of life, its irrelevant really, as mostly we are dazzled by the peripheral information and kept ignorant of the core facts,
Just like the analogy of the fighting arts /systems, you can be dazzled by the plethora of indigenous arts that span the globe we call home, well you can remain dazzled by the spectacle or maybe attempt to become a master of one or a few arts from your own secular point of view that is,
Or of course you can JKD (COMMON THREAD) the arts/systems and absorb the core/key components of which are useful as opposed too useless.
