Jeet Kune Do is not a "method of concentration or mediation". It is "being", it is an "experience", a "way" that is "not a way".
The art of Jeet Kune Do was formulated and developed between the years of 1964 and 1973 by the late, great Bruce Lee, aided by his friend and training partner, Dan Inosanto. The history behind 'the way of the intercepting fist' is purely academic, and can be found in countless forms of literature.
Jeet Kune Do was developed in order to counter-act the fact that no one fighting art could be totally relied upon in a streetfighting situation. Lee analysed as many different systems as he could lay his hands on, and finally selected elements from no less than 26 different arts, of which Wing Chun, Paqua, Western Boxing and fencing, Muay Thai, and Ju-Jitsu are but a few.
Bruce Lee would use a combination of techniques, concepts, and training principles from each of these systems, and then develop the skill of blending them together seamlessly. He also trained his body rigorously in order to better hone his skills. He believed that attributes were the key to excellence in combat, so he trained and studied with the specific goal of being able to use these attributes in any given situation.
Lee modified and developed techniques to suit his persona, which ultimately resulted in what we know today as Jeet Kune Do. This method of fighting has since continued to develop, under the careful instructorship of such prominent martial artists as Guro Dan Inosanto and Sifu Larry Hartsell. Arts such as Filipino Kali-Silat have been introduced due to their
effectiveness, and the grappling arts have been studied, modified, and adapted to a greater degree.
We at the Scimitar Martial Arts Association prefer not to practise Jeet Kune Do as it was whilst Bruce Lee was alive. Instead, we use the concepts of Jeet Kune Do as a template for our individual fighting system. Whilst a good deal of the techniques we deem relevant today differ from those taught by Bruce Lee in the 1970's, the underlying principles that made Jeet Kune Do so revolutionary 30 years ago are still adhered to in our teachings today.
My purpose in creating jeet kune do was not to compare with other branches of martial arts. Anything that becomes a branch would induce bad feeling. Once there is a formation of a branch, then things seem to stop. Students would labor for regulations and rules, then the meaning of martial art would be lost. Even today, I dare not say that I have reached any state of achievement. I'm still learning, for learning is boundless.
