My technique is a result of your technique; my movement is a result of your movement.
A good JKD man does not oppose force or give way completely.
He is pliable as a spring; he is the complement and not the opposition to his opponent’s strength.
He has no technique; he makes his opponent's technique his technique.
He has no design; he makes opportunity his design.
One should not respond to circumstance with artificial and "wooden" prearrangement.
Your action should be like the immediacy of a shadow adapting to its moving object.
Your task is simply to complete the other half of the oneness spontaneously.
In combat, spontaneity rules; rote performance of technique perishes.
Do not be tense, just be ready, not thinking but not dreaming, not being set but being flexible.
It is being "wholly" and quietly alive, aware and alert, ready for whatever may come.
The danger of training with the heavy bag is that it doesn't react to one’s attack and sometimes there is a tendency to thoughtlessness.
One will punch the bag carelessly, and would be vulnerable in a real situation if this became a habit.
