A martial artist is taught to use his own power to its fullest advantage. One maneuver that is taught is the art known as the kiai-cry. By drawing deep within himself, he is able to channel all of his power and concentrate it into one swift strike. This is used to begin a fight, and many times is able to end the fight within itself. The power of the attack is able to momentarily knock his opponent off balance, giving the edge to the attacker.
