Time, materials, and energy are limited. Reduction is sometimes necessary, but the burden should not automatically fall on those with the least room to spare. Sǔn explores decrease and increase, including modest offerings and carefully measured help. It does not call every loss good or require readers to prove their worth through continual sacrifice.
Identity and line order
Sǔn is hexagram 41 in the traditional King Wen sequence, with symbol ䷨. The lower trigram is Duì ☱ and the upper trigram is Gèn ☶; their traditional images are lake and mountain, respectively. Count the lines from the bottom: 初九、九二、六三、六四、六五、上九. A solid line is yang and a broken line is yin. Nine and six in the line labels designate yang and yin; they are not additional line numbers.

Hexagram statement
損：有孚，元吉，无咎，可貞，利有攸往。曷之用？二簋可用享。
Original editorial rendering; not a quotation from Legge: Decrease: with sincerity, great good fortune and no blame. One may remain steadfast; it is beneficial to have somewhere to go. What should be used? Two food vessels may serve for an offering.
Legge explains Sǔn as decrease while acknowledging the difficulty of interpreting the hexagram. He reads the use of two offering vessels as sincerity expressed even through modest offerings. The proportions of ancient ritual cannot become a direct demand for a modern payment or donation.
Today, ask whether a reduction meets a real need, whether the burden is reasonable, and whether basic conditions remain intact. Simplicity is not carelessness, and the value of giving is not measured only by quantity.

Interpretations in the Ten Wings
The Commentary on the Judgment and the Commentary on the Images belong to the commentarial collection known as the Yìzhuàn, usually called the Ten Wings. Below, these commentaries are kept separate from the hexagram and line statements, followed by modern learning applications.
The Commentary on the Judgment speaks of decreasing below to increase above, while emphasizing acting with the time. The Commentary on the Images uses a lake below a mountain and proposes restraining anger and desire. The former has an ancient distributive order behind it; the latter concerns cultivation of anger and desire.
Today, reflect on unnecessary consumption and impulse without using self-cultivation to demand unconditional concessions from vulnerable people. Who loses and who benefits should be visible and open to discussion among those involved.

The six lines, from bottom to top
初九 · Willingness to help also needs measure
已事遄往，无咎，酌損之。
Original editorial rendering; not a quotation from Legge: Set aside one's affairs and go quickly: no blame. Measure the decrease carefully.
Legge reads the first line as suspending one's own affairs and hurrying to help, while explicitly considering how much to contribute. The final instruction to measure the decrease must not be omitted.
Before agreeing to help, explain the time and work you can offer. Sincerity and limits can coexist. Making excessive promises you cannot fulfill may not truly help the other person.
References: zhouyi-41, legge1882-41
九二 · Some help need not damage your own foundations
利貞，征凶，弗損益之。
Original editorial rendering; not a quotation from Legge: Steadfast correctness is beneficial; setting forth brings misfortune. Increase the other without diminishing oneself.
In Legge's reading, increasing without decreasing means benefiting another without diminishing oneself. It is not simply a demand to give away more resources.
Sharing experience you have already organized or pointing out a reliable starting place can help. Seek a sustainable method first; exhausting yourself need not be proof of goodwill.

六三 · Changes in numbers do not determine a relationship's worth
三人行，則損一人；一人行，則得其友。
Original editorial rendering; not a quotation from Legge: Three people travel: one is reduced. One person travels: a companion is gained.
Three losing one and one gaining a companion depict changes in grouping. Legge preserves the pairing structure; it cannot mechanically decide who should be excluded.
Today, examine the division of work a collaboration actually needs. More people are not necessarily more effective, and fewer are not automatically closer. Choices require practical reasons, not elimination of members by hexagram numbers.

六四 · Reduce the problem, not merely the resources
損其疾，使遄有喜，无咎。
Original editorial rendering; not a quotation from Legge: Reduce the ailment; prompt help brings joy. No blame.
Legge translates jí as bodily illness and explains an image of inability to carry out affairs and the need for timely help. The joy in the text cannot become a guarantee of recovery from an actual illness.
In ordinary affairs, remove a process that repeatedly creates burdens, giving people room for necessary work. Actual physical or mental health requires separate, appropriate professional grounds.
References: zhouyi-41, legge1882-41
六五 · Reduction and receiving help can occur in the same hexagram
或益之，十朋之龜弗克違，元吉。
Original editorial rendering; not a quotation from Legge: Following Legge's interpretation: someone brings an increase, a gift of ten pairs of tortoise shells whose givers accept no refusal. Great good fortune.
Tortoise shells and ten pairs give this line a setting of ancient valuables and divination; Legge describes receiving assistance. It shows that not every line in Sǔn concerns loss alone.
Today, allow yourself to accept suitable help and explain its use and responsibilities. Ten pairs cannot be converted into a monetary amount, nor establish that an investment or gift will certainly arrive.
References: zhouyi-41, legge1882-41
上九 · Let benefit arise without requiring one side to lose
弗損益之，无咎，貞吉，利有攸往，得臣无家。
Original editorial rendering; not a quotation from Legge: Increase without diminishing oneself: no blame. Steadfast correctness brings good fortune; it is beneficial to have somewhere to go. Gaining servants beyond one household.
Legge reads benefiting others without diminishing oneself and gaining many supporters, while admitting that the passage's meaning is not fully clear to him. That interpretive limit should remain explicit.
Today, reduce duplicated work or share useful information so that both sides benefit. Ancient acquisition of servants does not authorize recruiting, controlling, or demanding unconditional involvement from others.

Making an event a little lighter
Original modern scenario
A group lacks money and time but wants to retain many decorations and activities. Members first identify what participants most need, then remove elements that do not affect the central experience and reserve their energy for clear explanations and practical care.
One member offers extra help. The group asks her to state what she can manage instead of assuming that more is always better. Work is redistributed for those already overloaded, rather than pressuring them with the claim that everyone is contributing.
Sǔn here becomes a reasoned, measured reduction. Its result depends on whether shared needs are better served, not on the idea that cutting more makes someone more virtuous.
Misreadings to avoid
-
Sǔn does not require accepting exploitation, abandoning basic needs, or donating resources unconditionally. The historical order of decreasing below to increase above is not a direct modern obligation.
-
Illness, tortoise shells, and numerical imagery do not predict health, money, or fortune, and cannot decide important financial commitments for anyone.
Three practices
-
Name something you plan to reduce and explain the practical purpose.
-
Identify who bears the reduction, who benefits, and whether renegotiation is needed.
-
Find a way to help without damaging basic conditions.
Related hexagram
Yì — Increase (hexagram-42)
Sǔn and Yì both examine who bears decreases and increases and where they flow. Decrease is not simply bad and increase good; specific conditions and effects matter more.
A closing question
While reading Sǔn, ask: after this part is reduced, is what truly matters being cared for better?
Textual note
The first line adopts the “已” variant explicitly listed in the base edition; the main text has “祀”, while the Commentary on the Images also writes “已事”.
