Jung Sim Do is a traditional Korean art, having its roots in the temples of Korea. To understand the history and true meaning of Jung Sim Do, we must first look at it's origin from the Chinese arts. The first form of martial arts reached China from India as a companion to the Buddhist religion.

Bodhidharma, or Da Mo as he is known in China, made his way to the Shao Lin Temple after a disagreement with Wu Ti, Emperor of the Liang Dynasty. He was welcomed openly by the monks and he began to teach them in his Dhyana doctrine (known as Ch'an in China, Son in Korea, and Zen in Japan). The Shao Lin monks grew mentally strong from Da Mo's instruction yet they grew physically weaker due to a lack of exercise. Da Mo countered this effect by teaching them a set of techniques which he had developed called the 18 Hands of Lohan. These simple techniques are believed to be the basis of what then became Shao Lin boxing. With time these techniques were expanded into a complete fighting system known as Chuan Fa.

Buddhism and Chuan Fa both made their way through China and finally into Korea where other Buddhist temples were established. In Korea there are believed to be three major Martial Art roots from which other Korean Martial Arts were formed: Koong Joong Mu Sool (Royal Court Martial Art), Sado Mu Sool (Family or Tribal Martial Art) and Bulkyo Mu Sool (Buddhist Martial Art). The art of Jung Sim Do proceeds directly from Bulkyo Mu Sool.

At the age of 14, Master Liam Kil Choi, the founder of the Jung Sim Do Federation, started his martial arts training at the first YMCA of Korea which opened shortly after the end of the Japanese occupation of Korea. Master Kil Choi was the first student to receive a black belt at this school. At the age of 18 Master Choi decided to pursue a more regimented and traditional form of martial arts training. Master Choi entered a Buddhist monastery where he studied for the next 30 years.

Shortly after leaving the Buddhist monastery Master Choi moved to the United States where he founded the United Jung Sim Do Federation. The name Jung Sim Do literally translates to "straight mind or single mind way". The name clearly represents the teachings of Jung Sim Do where we are taught that the mind always controls the body- especially under severe physical stress. The philosophy of Jung Sim (Jung Shin) is a well known philosophy in the traditional Korean arts, where their common goal is to promote mental concentration and focus. In 1980 Master Choi stepped down from the presidency and awarded the presidential position to his highest student, Master Sun Cheung, who presently heads the United Jung Sim Do Federation.
