Unsibanbon is one of the main teachings of Jeung San Do. Wun means "origin" or "primitive" and Shi means "beginning" or "start". Ban means "reverse" or "opposite" and Bon means "origin" or "base". Its literal meaning is that returning to the origin.
Before understanding Unsibanbon further, it is recommended that you understand both Cosmic year and Gaebyeok because Unsibanbon can be explained in more detail in the context of Cosmic year. The one constant in the universe is change, and at the time of the Autumn Gaebyeok, the direction of that change is returning to the origin. In our lives we often have the desire to return to our origins whether it means returning home after a long journey, discovering our ethnic and cultural roots, seeking the original purpose of our lives, or returning to the origin of life through meditation. The practice of returning to the origin is discovering who we truly are. It can also entail solving a problem at its root.
Why Unsibanbon is important?
According to the eastern philosophy, everything is changing and it has its own cycle. It is not difficult to find a cycle. Even our planet earth has its own cycle. Spring, Summer, Autumn, and Winter. This cycle is divided with four different seasons, but the principle below is alwaysyin and yang. When yang reaches its end, it must return to its origin. Just like a cannonball shot to the sky directly, it goes up to the sky and at a certain point, it returns to the ground. This action of return at the turning point is called Geukjeukban. As it is explained above, earth's four seasons can be contained in yin and yang. Spring and summer represent yang and autumn and winter represents yin. When summer reaches its end, just like a cannonball reaches its turning point, it returns to its origin from its farther-reached-end. This principle is important because Unsibanbon is happening regardless we acknowledge it or not. Also, it is important to accept and do our action with Unsibanbon this time of our life because it is natural like a shot cannonball returning to the ground from the sky. For this reason, many people meditate to be back to their origin. Quote from Dojeon
