So when does JKD simply evolve and look like MMA? Or will we always be able to tell what it is just by observation?
One way of looking at it:
Jiddu Krishnamurti:
"When you call yourself an Indian or a Muslim or a Christian or a European, or anything else, you are being violent."
Krishnamurti emphasized direct experience over labels and doctrines.
This idea is also expressed in some Taiji practices at a certain level of mastery, where transcending rigid forms and labels becomes key to deeper understanding and freedom of movement.
Wang Yongquan:
"Follow the rules and break the rules, break the rules and follow the rules. Only when you practice to this level can you achieve emptiness without stagnation, freedom of movement and stillness, formlessness and imagelessness, and the whole body is transparent."
Krishnamurti also said:
"Truth has no path, and that is the beauty of truth, it is living."
This directly applies to JKD’s core philosophy—it is not a rigid system but an evolving, adaptable approach to combat. Bruce Lee rejected the idea of JKD being a "style." If JKD truly follows its own philosophy, then its evolution depends on the practitioner’s level of awareness.
Seeking to label or define it would seem contrary to its core principles. "It" does not evolve; rather, practitioners using this philosophy as the basis for their own self-inquiry evolve.
One might look at who the teacher was that a practitioner followed / trained under
to understand the "practitioners" reflection " look/usage " of this within their movements.
