Re: The MOST important technique?
good post Larry, you have described how I have learned (or am supposed to learn) Aikido. I'd also say this is the most important technique so to speak, as if you do as you say...all else will follow correctly.
We get into anything else, well it just becomes an attachment so to speak. that is if we concentrate on physical aspects, it becomes a physical attachment, we assign spiritual value to something, well that would be an attachment, and mentally...well that too!
Mike above I think kinda elludes to these things as being road blocks to releasing KI, i have to say, I agree with him at least philosophically speaking.
As Lynn Seiser says all the time...just get out there and do it!
