Decrease

Giving from what you have — the hexagram of diminishment that is, at a deeper level, an offering. To give genuinely, even from limited means, is a form of sincerity that opens what calculation closes. Loss is real here, but it is not the end of the story; what is given rightly returns.
The image. Mountain above the lake — the still and solid above the open and giving.
Offer what you genuinely can, simply and without resentment. The decrease is real but its orientation matters — giving from the heart, even a little, opens something that holding cannot.

Every hexagram is two trigrams — the lower one beneath the upper. This one is Duì below Gèn.
