kiai

hello. could someone shed some light on the kiai for me? i know it helps with the attack but i forget how.

You should do a seach on the forum, it has been discussed many times by various Sensei's and instructors.

From a mental viewpoint he kiai helps direct your focus.

From an energetic viewpoint it causes the contraction of the diaphragm and intercostal muscles.

thanks guys

It corresponds to the Maxim from the Tao Te Ching "Empty out but be full!" You are emptying yourself of ethereal impurities but refilling yourself with purest Ki.
