What does it mean, 'inner' and 'outer trigram' (popup)
Wind below Lake: things never stop anywhere, they move on an on. They come up, arrive at their fullest potential, and go down again. It is useless to fret about this decline, it is an essential part of the entire universe. Make the best use of it, accept it for what it is and acknowledge its worth. In society old age has a big value. Maybe your strength will lessen (the ridgepole starts bending), but your wisdom has grown. Every situation has its rise and decline, and every phase has its own value.
Xun is also the blueprint, with Dui: the blueprint of society. The way generations follow each other, rising and declining on and on.
Ideogram of the hexagram name: the first (upper) character is a big person: big. The second character is a foot on a road and a skeleton over a mouth: a distorted mouth. A description of passing over a mouth or cleft in a mountain. In other old characters a stack of bones: vertebrae: the ridgepole of the body (above, the character at right).
Dà Guò is a big mountain-pass, it means to go beyond the limit, surplus. A passing which is usually irreversible. Also the transition from active life to old age. It is used for serious transgressions, especially regarding rules, like in a school or army. But also in a positive sense: surpassing others with an asset. Better or smarter. Another meaning is to transfer accounts.
The 'Great Image' says: a marsh over the trees (or Wind below Lake): Great excess. The noble one stands alone without fear, retreats (or retires) without melancholy.
Hex.28 is the contrast of 27, which is about sustaining and supporting life.
Hex.28 is the change from active life to retirement, or peak to decline, or any inevitable change in life, and accepting it.
