You attract what resonates with your own nature. Thus you become the center of a life which reflects yourself.
When the central force is narrow, it creates a dogmatic group, and these groups can be very dangerous. Even when it is only a group of ideas in one head. But a broad rich mind will gather high values.
On a spiritual level, being one with a group can mean being one with all things and people in your life. When your mind is universal enough, the borders disappear, you ARE your life.
Hex.45 is the opposite of hex.26, the hexagram of higher values and culture. In 45 the assembly is of peers. Nobody is specifically more or less than another, and there is no need for ambitions.
It is complementary to 46, the labor of ascending step by step. In 45 there is no need for rivalry, people do things together, their number makes their strength.
CUÌ. A jacket (1) with a sign on it (3): a uniform jacket of a soldier, servant or adherent. This character also means sudden death or accident. At the top 'plants' (2): uniforms like grass. FE4975, [M6880], GSR.490m: assemble, bundle, heap or a lot, collection, dense vegetation. I think what anthropologists call 'union mystique' is also part of this hexagram's meaning.
CUÌ: gather together.
The trigrams: Lake on the Earth:
A marsh on the earth, gathering. The noble one puts weaponry out of sight and is alert for danger.
Earth carries all creatures. When they all gather in the fertile marsh, things can easily get out of hand. People and animals can relate to those who resemble themselves, but see enemies in those who are different. Temples and sacrifices create a bond which goes higher than everyday disagreements, they create mutual connections.
