Instead of opposing force by force, a JKD practitioner completes his opponent's movement by 'accepting' his flow of energy as he aims it, and defeats him by 'borrowing' his own force. In order to reconcile oneself to the changing movements of the opponent, a JKD practitioner should first of all understand the true meaning of Yin/Yang, the basic structure of JKD.

Yin Yang (Symbol of the Tao)

The importance of the Yin Yang is to show that opposites occur in nature. In essence, they must occur, for without light how would we know what darkness is? These opposites are in constant interplay, meaning nothing is truly an independent entity.

The Arrows

The arrows emphasize that here is dynamic interplay between the opposites. We & nature are constantly changing. We go from action to rest, or from pliable to firm, from being awake to being asleep.

The Writing

The Characters say 'Using no way as way, having no limitation as limitation'. This is the philosophical essence of Jeet Kune Do. We use no set 'way' to reach our goal, and we do not impose limitations on ourselves that will keep us from approaching our unlimited potential.
