Get it, get what?
My post to Mr. Carnejo was simply to point out that the food comparison to knowledge, as the original analagy of water in a glass was not about differnent types of food that taste different, but about quantity, and being able to add more to the glass of knowledge.
The point of my using this method of questioning, is that I don't have all the answers, just the ones that work for me in my lifetime of experience, and if you have a better answer ... speak up!
I can't get any simpler than that.
The reality of the cup of knowledge, is that it is always growing as we continue to learn, it is never half full, or half empty, but barely containing any knowledge at all in the great amount of knowledge that is available. We have but to learn that to truly see how the empty your cup adage is for you to shut up until you learn enough to contribute in a positive manner.
Why do you think people smile at you, slap you on the back, and tell you that you are doing just fine when you bring up questions from techniques in other martial arts that resemble techniques found in Aikido? Positive reinforcement that deny an answer but forces you to find an answer within your present level of practice.
At least that is what it should be over most teachers and students who really don't know, or don't want to confuse your learning the foundations of Aikido.
You aren't the only one.
I am a minority within a minority that cross trains, searches for answers that cross over into all martial arts, and still maintians the integrity of Aikido.
There is no distillation, but it is more like a filing system with many subfiles and variations in each category.
Within Shihonage, I find a variety of arm manipulations not only found within variations of Shihonage, but many grappling, jujitsu, and plain old school of hard knocks lessons that can be changed or varied by the simple name of shihonage. Do you?
Part of putting Aikido into pillars of learning is one explanation to letting the mind lead the body into a general direction of movement but have the ability to us transition, or variations as the venacular of Aikido, so you are not locked into any technique as a set form never to be varied from.
Cup of knowledge? Distilling techniques into being the best they can be and calling them Aikido? Get real.
We learn A, B, C .... but eventually we don't think of the letters, but we see the words which bring to mind pictures, and meaning.
Pillars of Aikido? Same thing.
How many words can there be? About as many as there can be variations for Aikido.
If you get that, then you understand why the glass of knowledge is never empty, but why you are always filling a bigger cup.
