The high blue belt in ChunJiDo has a black stripe through the center. This stripe is a reminder of the goal to achieve black belt and a reminder that training in the martial arts is a continuous journey. The form done at the high blue belt level is Seunchin. Seunchin means ‘Strength of Ten’ and is considered to be an internal kata because of the use of muscle tensing and relaxing along with steady, deep breathing to generate power. Seunchin is credited to Chojun Miyagi, the founder of Goju-Ryu Karate.
