Proper kiai ought to be considered inseparable from breathing. Power and Strength One of the advantages of kata practice is the fact that each individual can find his own pace and perform to it. Therefore, there can be no standard way to judge what power and strength should be put into what moves, although it can be said that a good kata is a powerful kata. True strength is often hidden within and one must be experienced to be able to see this. Moreover, each move must be executed with in intensity inseparable from power and rhythm.
Correct rhythm means more than dance-like movements.
In fact, if you really imagine actual, moving opponents as you perform your kata, it will certainly come alive. Because each individual is different, each individual will allow a particular kata to express his mental, physical, and spiritual qualities, just as each individual uses a language differently from another, conveying the same message with slightly different emphasis and stresses. Balance Quite simply, the importance of balance cannot be exaggerated. Physical and mental balance is controlled through the center of gravity, located in each of us, in the lower abdominal area. In part, learning a new kata is a process of learning a new system of balances.
