Hwa Rang Do’s Founder, Dr. Joo Bang Lee, comprised the curriculum of his martial art within the framework of both Musool (무술 武術 – martial skills) and In-sool (인술 仁術 – healing skills).  The martial art skills (or Musool) are divided into four categories: Nae Gong (內功 – internal training), Wae Gong (外功 – external training), Mugi Gong (武技功 or 武器功 – weapon training), and Shin Gong (神功 – mental training), which are classified into 280 different categories of over 4000 techniques. He also divided the healing aspects (or In-sool) into the six categories of Ji Ap Sool (指壓術 – acupressure), Ch’im Gu Sool (針灸術 – acupuncture and moxibustion), Yak Bang Bop (藥方法 – herbal medicine), Jup Gol Sool (接骨術 – bone setting), Hwal Bop (活法 – Special Aids), and Ki Ryuk Sool (氣力術 – Ki Power healing). Hwa Rang Do is not only an art based on self-defense, it is also a healing art.

Along with having this incredible array of skills, one of the most important priorities of all Hwa Rang Do practitioners is the development of their character. Their mentality is based from the Hwarang O-Kae (오계 五戒 – Five Rules), the code of ethics of the ancient Hwarang. These standards are augmented by the Hwa Rang Do Kyo Hoon (교훈  敎訓 – Code of Ethics), which are the Dr. Joo Bang Lee’s nine principles of human morality. Hwa Rang Do training is not only about fighting techniques. Hwa Rang Do first counts a strong human moral mentality. That is why the “Way” of Hwa Rang Do (花郎道) includes strong discipline as well as the study of philosophy and human morality.
