Gŭ, hexagram 18

Can o' worms

  Everybody has alien influences embedded in his soul or body. Many are hidden; one does not even know they exist. It seems as if they are part of the personality. Especially those one collected in childhood. In order to live one’s own life and one’s own fate, one has to get rid of them. The more one succeeds, the more happiness, strength and health will come back. Every influence makes a distance between one’s mind and God, or however one calls the inner essential being. Really reaching your god is very difficult – except when one does reach him, and then it turns out to be the easiest thing in the world. You wonder why you did not know it was – it is because the distance is made of thinking, but to reach what you call god is made of being.

The trigrams: Wind below Mountain.
At the foot of the mountain the wind blows: decay. The noble one inspires the people to raise virtue. To overcome the infection of bad influences, one needs to boost the energy and joy in life by inviting a fresh wind.
