JuCheYeong (主體靈) is the strongest spirit within each individual that governs their thoughts, memories, judgments, and all actions, representing ‘me’.
It is the most powerful spirit within a person, forming the essence of the consciousness of ‘I’, or the ego (self). It can be considered the spiritual subject that forms and maintains all human relationships, including those with oneself, family, relatives, friends, communities, and nations.
In English-speaking contexts, this concept can be expressed as ego, self, or core self.
