Ok, riddle me this?! How did you come to this conclusion? How do so many people come to this conclusion concerning Aikido?
movement for the sake of movement does not mean understanding behind the move. One needs to understand why we move certain ways, not only how.
O'Sensei once said that a student could learn all the basics of aikido if he practiced just three techniques: 1)tai-no-henko, 2)morotedori-kokyuho, and 3)suwariwaza-kokyuho. I have my own theory of this based on basic mechanical laws but others may not have a clue. The explanation to this only becomes obvious over a very long period of time. Ever wonder why you can do morotedori on weak people but impossible to move even an inch on people with muscular build. Not bragging but I think I can move everybody no matter what build because I know mechanics theory which I applied to very muscular people in the dojo. The move is trvial but not obvious if one does not understand mechanics..
The dojo is a laboratory and every aikido practice should be treated as experiments. One should postulate theories about techniques which should undergo tests through trial and error. If a theory holds true for all techniques, then it becomes a principle and you do this over time to collect principles. A true master collects principles, he does not collect techniques imo and this takes a lot of time..
