Some folks just aren't the question machines that folks tend to be on these forums. They're creative thinkers and leaders in life - but when they get to the dojo they want to work out, work hard, and have a good time. If it works for them then their training is valid for them.
Not everyone who trains in martial arts seeks to be a teacher, a disciple who will carry on the system, or a master. Some folks just like to train.
Just like some folks like to post on these forums, some like to read, and some avoid them like the plague. All are valid.
But if you do want to understand all the particular esoteric elements of your art, your practice, and your tradition - then you should be sure to seek that out. Funny thing is...I have a sneaking suspicion that those elements vary from person to person.
Because in the final analysis - everyone will keep what they understand and do well, discard what they don't like and/or don't do well, and add their personal signature to what they're doing. In cooking, in design, in martial arts, in governement, and in life.

Profound am I, so early on Saturday.
Grand thoughts for one so small, they are
Perhaps more coffee should I seek
