십이 [shibi] (sino-korean)
열둘 [yeoltul] (native korean)
The number “twelve” symbolizes twelve types of human character. During our lives, we will meet twelve very different types of people and learn to get along with them. These will be people whose personality types are similar to January, February, March, and so on – to all the months of the year.
Another number “12” corresponds to the twelve entities: grandfather, grandmother, husband, wife, son and daughter, that is, six people, each of whom has a soul and a body. When these twelve entities are united, there is a sphere of perfection.
