The image of the jar has emerged in various cultural contexts. The purpose of our study is to understand its symbolic meaning. We examined it from the perspective of analytical psychology. This involved an analysis of the manufacturing procedure and function. We also studied stories of jars such as Sikjang Mountain folktale and the Marriage at Cana of the New Testament, and the architectural works related to Buddha’s Sarira. We find that it serves as a symbol of the space in which the psyche can achieve self-actualization.
