The Elemental Approach

Taijutsu, the ninja self-protection method, takes an elemental approach based on the Go-dai "five-elements". 

Chi     Earth stability, the attitude of confidence and strength.
        The confrontation is won before it has started. You stop
        them in their tracks. You are immovable as a majestic
        mountain or a mighty oak tree.

Sui     Water responsiveness, the attitude of fade and strike.
        You withdraw from your aggressor's attack, and respond
        with a blast of power. You are as a wave in the surf
        rising back and then crashing on the shore. 

Ka      Fire expansiveness, the attitude of foresight. You
        perceive the potential for attack and are committed to
        stopping the aggression the moment you perceive it. You
        are as a fireball hurling forward.

Fu      The attitude of intellect. You are free moving and
        skillful enough to know exactly where you need to be
        in order to take control of the aggression, positioning
        yourself to take advantage of your momentum. You are like
        a cloud of smoke that one tries to grasp as you slip and
        curl from between his fingers and out of his grip.

Ku      The void, the source of all elements. You use your
        skill to face unknown attacks and acquire the appropriate
        attitude in response.
