Kata, waza and natural movement
To me aikido is a martial art. As such the techniques must possess a potential for brutality, being designed for maiming or killing the opponent. Aikido training is not childish play. The required frame of mind is somewhat like that of combat training in the Army.
If you have had such training you remember how at first you and your unit practiced without ammunition, then with blanks, until finally your unit practiced with live ammo and artillery support, moving through terrain attacking and firing at active, but nonhuman targets. These exercises were prearranged typical situations and you walked through them before actual training. (In budo this kind of training is called kata). To enhance safety, orderliness and discipline was stressed, just like in the dojo.
Such training methods have proven effective since they have allowed humans to function effectively even under the extreme stress of risking death or mutilation.
There are five basic human needs sieved out over time by evolution: violence, sex, food, social recognition and sleep. As resources are limited and peoples´ wishes differ, conflicts arise that may lead to violence.
Conflicts and violence is the subject of aikido. Let us use the yin/yang concept. In a real fight/conflict there are two opposing wills. This is a yang-yang situation where none of the combatants wants to yield. And there are no rules.
