Kata are a sequence of basic, intermediate or advanced techniques which are meant to be performed with technical accuracy. The kata of karate-do are logical arrangements of blocking, punching, striking, and kicking techniques in certain set sequences. Each kata begins with a blocking technique and consists of a specific number of movements to be performed in a particular order. There is some variation in the complexity of the movements and the time required to complete them, but each movement has it's own meaning and function and nothing is superfluous. All kata, require and foster rhythm and coordination. Training in kata is spiritual as well as physical. They may be described as choreography of attack and defense, a ritual of technique and movement; the Waza are the application of the latter and the Do their spiritual aspect."Their exercises are battles without bloodshed."
Josephus Falvius
