Hexagram 41 is 損 (Sǔn), usually rendered as Decrease or Diminishing. In the King Wen sequence it places Gen (艮 gèn), Mountain, above Dui (兌 duì), Lake. Read from the ground up, the picture is a lake at the foot of a mountain: the water gives up some of its depth, and the mountain stands the higher for it. What is taken from below adds to what rises above.
This is the working sense of hexagram 41. Something is being drawn down or given up on purpose — resources, expenses, ambition, self-regard — and the reduction is not loss but redirection. Sǔn is the hexagram of the deliberate cut: the branch pruned so the tree can carry fruit. It sits directly before Hexagram 42, Increase (益 yì), and the two are a matched pair. Decrease done rightly is what makes later increase possible.
The two trigrams and their picture
Gen, the Mountain, is stillness and keeping. Dui, the Lake, is openness and quiet joy. Placed together, the outer situation asks for restraint and firmness while the inner mood stays willing and unresentful. That combination is the whole instruction of hexagram 41: you reduce without bitterness. The lake does not grudge the water it gives to the mountain.
There is also a human reading in the line structure. The classical commentary sees a strong line drawn from the lower trigram up to strengthen the upper — the individual giving to the collective, the ordinary supporting the high. When decrease flows in that direction, from self toward something larger, it holds. When it runs the other way, stripping the base to gild the top, it does not.

The overall counsel of Sǔn is that decrease, undertaken with sincerity, brings good fortune. The old text pairs it with a small, telling image: two modest bowls are enough for the offering. You do not need an elaborate display to be sincere — a plain gift given honestly outweighs a lavish one given for show.
For a practitioner, the reading is straightforward. This is a season to spend less, claim less, and hold less tightly. Ask what is genuinely surplus and let it go toward where it does more good. The emphasis falls on honesty rather than scale: what matters is that the giving is real, not that it is large. Constancy in this — steady, unforced reduction — is what makes the phase favourable rather than merely thin.
The Image and its lesson
The Image of hexagram 41 looks at the lake wearing away the base of the mountain and draws a lesson about the inner life. The counsel is to curb anger and restrain the appetites — to decrease, in oneself, the impulses that swell and demand.
This is the quiet centre of Sǔn. The outward economy the hexagram advises is easy enough to grasp; the harder work is inward. Anger and craving are the things most worth reducing, because they cost the most and return the least. The Mountain-over-Lake picture says: let the settled stillness above draw down the turbulence below. What you decrease in temper and want, you gain in clarity.
Practical guidance
In work, hexagram 41 favours consolidation over expansion. It is a phase for trimming commitments, cutting what is costly and unproductive, and investing the freed capacity where it compounds. Do not read decrease as decline; read it as making room. A budget deliberately tightened now is the ground of later increase, not a sign of failure.
In relationships, Sǔn asks what you can give up without keeping score — an insistence on being right, a slight nursed too long, time you were guarding for yourself. Giving that flows upward, from the individual toward the shared bond, tends to strengthen it. Sincerity again outweighs grandeur: the small honest gesture lands where the performed one does not.
On timing, this is not a moment to push or accumulate. It is a moment to pare back and hold steady, trusting that a well-made reduction sets up what comes next. Treat all of this as tendency rather than verdict. Hexagram 41 describes the grain of the situation and where it is inclined to move; it advises restraint, it does not command an outcome.

Changing lines and where it shifts
When lines in a cast come up as changing (a 6 or a 9), they mark the active edge of the situation and point to a second hexagram — where the moment is tending. In Sǔn the lower lines often speak of giving in the right measure: helping quickly but not stripping yourself bare, knowing when your contribution is enough. The upper lines turn toward the fruit of honest decrease, where reduction has done its work and begins to return as gain.
Because Decrease and Increase are a mirrored pair, the natural drift of hexagram 41 is toward Hexagram 42, 益 (Yì), Increase. What is given up cleanly at the bottom of the cycle is what flows back at the top.
