I understand your frustration...
but what is fundemental to Moo Duk Kwan TSD has been passed down, one doesn't need to cross train in other arts to discover this.
Philosophically, MDK is a pretty deep art. HK devoted entire books to developing his school of martial virtue. Unfortuneately, many of these books are not going to translated into English anytime soon. All of this is very interesting and valuable, but if my intent was to study philosophy, I could just as easily study a number of other books...which just so happen to be the ones that HK studied...and glean as much or more depth. HK was very clever and creative, but he was no Buddha.
Technically, the MDK is pretty shallow. Almost the entire curriculum has been imported form other sources where the context and usage of this or that technique has been preserved. This information was not transmitted during its importation.
I totally respect those who wish to train in more than one art, but if you think you know all there is to know about the one art you study to then study others then you are gravely mistaken.
Let me put it this way. I study Tang Soo Do. That's it. I have trained in a whole bunch of other arts and I have rank in them, but my understanding of those arts is applied back to my TSD training. This multiple perspective view allows me to see what I study in greater depth.
What you are all discussing here which relates to the origin of certain Hyungs is historically interesting, and revealing yet most of which is not known or set in stone, and this does not add anything to what can be passed down and taught to me through the art i study.
This is foolish. This isn't just a discussion about the historical origins of the hyungs, its a discussion about their technical usage and application. It's about learning how to actually use the hyungs to fight...like they were meant to in the first place. All of that wasn't taught in the MDK. Hwang Kee learned the hyungs from books and knew none of the applications. If he had, then the curriculum of TSD would look very different then what it is now...and we would be left with much less philosophy of Martial Virtue.
If you are not getting the knowledge and wisdom through your art then i would question who it is who teaches you.
With a top down hierarchical structure extant in most KMA, I wouldn't necessarily single out your teacher as being solely responsible for the transmission of an art's "knowledge" and "wisdom". Other people set the curriculum and standardize it. Other people choose what they think is important and make people below them do that.
And then, I think you really need to define what "knowledge" and "wisdom" you think you are learning. Pretty much every technique that you would need to defend yourself in most situations can be found in naihanchi. Do you practice this form with that much depth?
Finally, to say without cross training, my hyung will never get beyond interpretive dance is a very silly and empty thing to say. A dancer would not know any application but to simply replicate moves for the sake of it.
Unfortunately, its too true in too many dojangs. Most students have no clue regarding application to their forms and just practice the moves to practice the moves. It's an interpretive dance.
With that being said, lets do a little test, what do you know about naihanchi?

PS - I apologize if all this seems confrontational, it is, but I think we as Tangsoodoin need to be challenged more on the depth of our technical knowledge in order to understand the gaps in our curriculum. I'm not trying to pick a fight or be mean-spirited, I'm trying to help my fellow brothers of the spear.
