Hello Aikido culture; I have been taught that the warmup exercize known as Happo-Undo, the 8 directional movement is symbolic of focusing on the task at hand. Such as methodically going thru the day with purpose and focused intent; get food, pay bills, see taxman,get gas, go to eat,etc... I also understand the foot/hand movements prep the trainee for bokken katas ,as well as grounding for better body movement. So my question to you all in the know is; Do you have any other metaphors or parallel teaching insights for the other basic warm-ups conducted usually prior to training? Example for tenkan might be the door-hinge explaination. Thank you all for any insights you may offer. Daniel.
