Greetings, again, everyone!
I hope this message finds you all in great health and spirits.
Similarly to the Chil Sung Hyung, I saw mention of the Yuk Ro Hyung in the 'Korean Karate...' thread and thought they deserved more attention.
The Yuk Ro Hyung were, at least, conceptualized in 1957, the same year that the founder, Hwang Kee, was presented with the Moo Yei Dobo Tong Ji. The text was the motivation for two sets of hyung, the Yuk Ro (Six-Fold Path) and the Sip Dan Khum (Ten Levels of Silk). Apparently, the Sip Dan Khum hyung are not taught outside of Korea. At any rate, they won't be the topic of discussion in this thread.
The Six-Fold Path is related to the Chil Sung Hyung in its intent of development. Where they differ is that the Chil Sung Hyung are intended to develop the artist as a person. The Yuk Ro Hyung are intended to develop the artist as a warrior.
The Yuk Ro are described as:
Du Mun - The Great Gate - As a martial artist, you must open your mind to information. Indeed, the gateway to the mind if often the most difficult to open, and why it is known as the Great Gate.
Joong Jol - Cut the Middle - As a martial artist, much of the information that passes through the Great Gate will be either useful information that is obscured by fluff, pure nonsense, or perhaps, purely useful knowledge.
Po Wol - Embrace the Moon - When you've cut through the middle and sorted what has passed through the Great Gate, embrace the information you've discovered and make it part of your energy.
Yang Pyun - High Whip - You will come to a point where your martial art skill will be at its highest, and as a warrior, you will be like a lone man, high atop a hill, wielding a whip, and no one will be able to touch you.
Sal Chu - Killing Hammer - Further down the road, you will have so much knowledge and power that you'll be able to kill with one blow, like a heavy hammer against your enemy.
Choong Ro - Seize and Capture - You will realize that with all your knowledge, it is not being untouchable or being able to kill with one blow that makes you a skilled martial artist, but being able to capture your enemy WITHOUT causing injury.
By practicing the Yuk Ro, you walk the path to becoming a great and noble warrior.
