What does it mean, 'inner' and 'outer trigram' (popup)
Gèn below Duì: Gèn is a real presence with solid intentions, not one with flighty actions. Dui is a place of an abundance of creatures. The wetlands where life is easy and joyful, where you can start a family or find friends or form a group.
Ideogram of the hexagram name: a halberd and a mouth. It means bringing together, which can be in big ways, like a whole country, or small, just two people. Hence in the judgment "Taking a wife" and in the image "Receiving people by emptiness". The meaning of the halberd is not really clear (yet).
Xián: together, all, both, total, unite, case or cover, complete, fully, generally, act together, union, harmony, universal, continual, everywhere, to move, to touch, influence, transform, dissatisfied, finish, resent, salt, salty. Xián you (unite have): have under control (the 9 provinces). Xián is exchangeable with Chéng: to become, turn into, to bring to completion, succeed, name of the city which brought people and ancestors together (see story). In the Mawangdui Yi Jing this hexagram is called qīn: respect; obey with respect, imperial. When respect is missing, then the other meaning of xián emerges: wounding with the mouth.
The 'Great Image' says: At the top of the mountain is a marsh: affecting. The noble one receives people by emptiness.
Hex.31 is the contrast of 41, Dimishing, which is about controlling your feelings and decreasing where necessary.
Hex.31 is about completion, uniting, harmony and influencing another to that effect.
