As in the attacking

techniques, many of the parries used in karate are 'focused'. That is to say, one's entire strength is concentrated at the point and the moment of impact, after which the muscles are immediately relaxed. As a result, pain or even injury may be inflicted with the parry alone, and the opponent sufficiently discouraged from attempting any further attack.

When parrying, however, you should always have a counterattack ready to follow up with. Be sure that you maintain a good posture and balance and try always to take advantage of your opponent's momentum and strength to upset his balance and posture.
