Abstract
One of the three old Korean scriptures, Sam II Shin Go, contains well defined concept of Ki. Sam II Shin Go means the teachings of God on Three and One. Its origin goes back to more than thousands of years. This scripture describes on the nature and origins of human beings and all other materials. According to this scripture, there are two kinds of Ki, i.e., One Ki[一氣], and Ki[氣]. The self-organization of One Ki results in a dynamic state of the interaction of three elements, Mind[心], Ki[氣],Body[身], In this paper, the difference in concept and properties between One Ki and Ki has been discussed including the nature of the self-organization of One Ki.
