"Lin" means "looking down from a height" or "being in a superior position ruling subordinates." It also has the meaning of "looking up from below" in a positive or negative sense. Therefore, there is a subconscious existence of hopes and wishes. The upper trigram, Kun, represents "earth"; the lower trigram, Dui, represents "marsh" or "lake." A "marsh" is a place where water is stored, such as the sea, a lake, or a pond. We know that water in ponds and marshes evaporates when heated by the sun, turns into clouds and rain, and falls back to the earth to nourish all things between heaven and earth. Thus, all things develop and grow. Water on the ground eventually flows back into ponds and marshes, bringing with it various things from the ground as food for seaweed or fish, enabling them to live and multiply. In other words, water on the ground flows into ponds and marshes, is stored, and becomes a place of outflow and inflow; during droughts, it is released from ponds and marshes to irrigate all things on the ground. This signifies mutual proximity, mutual assistance, and mutual dependence, with hope residing within. On one hand, the trigram Dui can be interpreted as "joy"; on the other hand, the upper trigram Kun can be interpreted as "compliance." Taken together, it means that those below are joyful (delighted) in expressing and requesting their opinions to those above; and those above, by complying with the opinions of their subordinates, bestow grace. Thus, they mutually complement each other. Therefore, it is named the "Lin" hexagram.
