損 Sǔn — Decrease
Mountain over Lake · Sacrifice · 山下有澤，損
Sǔn (損) is the forty-first hexagram in the I Ching — Mountain above Lake, the lake diminishes itself to nourish the mountain above. The character 損 means "to decrease," "to diminish," "to reduce," "to sacrifice" — it shows a hand (手) taking away (員), the act of deliberate reduction. This is the hexagram of sincere sacrifice: voluntarily giving up something of one's own to benefit something greater. The lake at the foot of the mountain evaporates its waters upward, diminishing itself to increase the mountain's moisture. But the I Ching teaches that this decrease is not loss — it is the most profound form of gain. The Xugua teaches: "Deliverance inevitably leads to loss. Hence Decrease follows" (解必有所失，故受之以損). After Hexagram 40 (Xiè, Deliverance), the necessary decrease that follows release — after the storm clears, what was excessive must be reduced to restore balance.

The Judgment (卦辭)
"損，有孚，元吉，無咎，可貞，利有攸往，曷之用，二簋可用享。"
Decrease combined with sincerity brings about supreme good fortune without blame. One may be persevering in this. It furthers one to undertake something. How is this to be carried out? Two small bowls may be used for the sacrifice.
The judgment of Sǔn is one of the I Ching's most detailed and nuanced:
Sǔn
Decrease · Sacrifice · Diminishing
損 — "decrease," "diminish," "sacrifice". The hexagram describes a time when reduction is necessary and virtuous — not as punishment or failure but as a deliberate, sincere act of giving up the excessive to nourish the essential. The lake diminishes itself not because it is forced to but because its nature is to flow toward what needs nourishment. This willing, natural decrease is the foundation of the entire hexagram's teaching.
Yǒu Fú
With Sincerity
有孚 — "with sincerity," "having trust". 孚 (fú) is sincerity, inner truth, the genuine heart. This is the essential condition: decrease must be accompanied by genuine sincerity. A sacrifice made reluctantly, resentfully, or for show is not true decrease — it is merely loss. True decrease flows from authentic inner willingness, from the sincere recognition that giving up something serves a greater purpose. When decrease is sincere, it brings 元吉 — supreme good fortune.
Yuán Jí
Supreme Good Fortune
元吉 — "supreme good fortune". 元 (yuán) is primal, original, supreme; 吉 (jí) is good fortune. Not just "good fortune" but the highest form of good fortune. The I Ching rarely uses 元吉 — it is reserved for situations of exceptional alignment between inner virtue and outer action. Sincere decrease produces the supreme good fortune because it aligns with the deepest law of nature: what gives freely receives abundantly.
Èr Guǐ
Two Small Bowls
曷之用，二簋可用享 — "how is this to be carried out? Two small bowls may be used for the sacrifice". 曷 (hé) is "how"; 二 (èr) is two; 簋 (guǐ) is a small round bowl used for grain offerings in ritual sacrifice; 享 (xiǎng) is to offer sacrifice, to present to the spirits. The most remarkable instruction in the judgment: in a time of decrease, even the simplest offering is sufficient. The normal sacrifice required many elaborate vessels and abundant food. But the I Ching says: two small bowls are enough. When sincerity is genuine, the form of the offering can be minimal. The spirits do not need extravagance; they need truth. Sincerity transforms even the humblest gift into a supreme offering.
💡 Key Insight: Hexagrams 41 and 42 — Sǔn (Decrease) and Yì (Increase) — form the I Ching's most fundamental economic pair. Sǔn teaches that decrease is not loss: when the lower (the lake, the people, the self) sincerely diminishes to nourish the upper (the mountain, the ruler, the higher purpose), the entire system benefits. Yì (Hexagram 42) will teach the complementary truth: increase flows when the upper gives to the lower. Together they reveal the I Ching's complete theory of circulation: wealth, energy, and virtue must flow — sometimes upward (Decrease), sometimes downward (Increase) — and the direction of flow determines the hexagram. The key principle: what matters is not whether you have more or less, but whether the decrease or increase serves sincerity (孚) and benefits the whole.
The Six Lines: The Art of Sincere Sacrifice (爻辭)
The six lines of Sǔn trace the various modes and degrees of decrease — from the swift sacrifice that helps others to the paradox that true decrease of self leads to increase received from heaven.
已事遄往，無咎，酌損之
When one's own affairs are finished, one should go quickly to help others. No blame. But one should weigh the matter and decrease oneself accordingly.
The basic act of decrease: helping others. 已事遄往 — "when one's own affairs are completed, go swiftly". 已 (yǐ) is completed, finished; 事 (shì) is affairs, business; 遄 (chuán) is swiftly, promptly; 往 (wǎng) is to go. First complete your own responsibilities, then swiftly go to help others. 無咎 — "no blame". Helping others at the cost of decreasing yourself is blameless. 酌損之 — "weigh the decrease carefully". 酌 (zhuó) means to weigh, to measure, to pour carefully (like measuring wine). The decrease should be measured, proportionate, and appropriate — not reckless self-sacrifice but considered generosity. The teaching: help others, but measure your sacrifice wisely. Give, but do not destroy yourself in giving.
利貞，征凶，弗損益之
Perseverance furthers. To undertake something brings misfortune. Without decreasing oneself, one is able to bring increase to others.
The paradox of decrease without self-diminishment. 利貞 — "perseverance furthers". 征凶 — "to advance brings misfortune". 征 (zhēng) is to advance, to campaign; 凶 (xiōng) is misfortune. This is not the time for aggressive action. 弗損益之 — "without decreasing oneself, one increases others". 弗 (fú) is "not"; 損 (sǔn) is decrease; 益 (yì) is increase. The most subtle teaching: sometimes the best way to help others is not to sacrifice yourself but to maintain your own strength. The yang line in the center of the lower Dui trigram is perfectly positioned — central, balanced, strong. If it were to diminish itself, the whole lower trigram would weaken. By maintaining its own integrity, it naturally benefits others — the strong center supports the whole structure.
三人行則損一人，一人行則得其友
When three people journey together, their number decreases by one. When one man journeys alone, he finds a companion.
One of the I Ching's most mysterious and profound lines. 三人行則損一人 — "when three walk together, one is lost". 三人 (sān rén) is three people; 行 (xíng) is to travel, to walk; 損一人 (sǔn yī rén) is to lose one person. 一人行則得其友 — "when one walks alone, one finds a companion". 一人 (yī rén) is one person; 得 (dé) is to find, to obtain; 友 (yǒu) is friend, companion. The teaching operates on multiple levels: cosmologically, it refers to the principle that three is unstable, two is complete — heaven and earth, yin and yang, self and other. Three creates jealousy, rivalry, and the necessity of exclusion; two creates partnership. In relationships, it means: a third party always introduces instability. In self-cultivation, it means: reduce your crowd, simplify your connections, and the right companion will appear.
損其疾，使遄有喜，無咎
If one decreases one's faults, it makes the other hasten to come and have joy. No blame.
The most personal form of decrease. 損其疾 — "decrease one's illness," "diminish one's faults". 疾 (jí) is illness, disease, fault, defect. The decrease here is directed inward: not giving up possessions but giving up one's own faults, weaknesses, and bad habits. This is the deepest and most valuable sacrifice — the sacrifice of one's own negativity. 使遄有喜 — "makes the other come swiftly with joy". 遄 (chuán) is swiftly; 喜 (xǐ) is joy, happiness. When you decrease your faults, others rush toward you with joy — your self-improvement is magnetic, drawing good relationships and good fortune. 無咎 — "no blame". The teaching: the greatest sacrifice you can make is to reduce your own flaws. This decrease costs nothing material but transforms everything relational.
或益之十朋之龜，弗克違，元吉
Someone does indeed increase him. Ten pairs of tortoise shells cannot oppose it. Supreme good fortune.
The supreme reward of sincere decrease. 或益之 — "someone increases him". 或 (huò) is someone, perhaps; 益 (yì) is to increase; 之 (zhī) is him. After sincere self-decrease, increase comes unbidden from without — heaven itself sends the reward. 十朋之龜 — "ten pairs of tortoise shells". 十朋 (shí péng) is ten pairs; 龜 (guī) is tortoise. Tortoise shells were used for divination and were among the most precious objects in ancient China. Ten pairs represent immense, uncountable treasure. 弗克違 — "cannot be opposed". 弗 (fú) is "cannot"; 克 (kè) is to be able; 違 (wéi) is to oppose, to go against. Even the most powerful divination cannot oppose this increase — it is decreed by heaven. 元吉 — "supreme good fortune". The teaching: when decrease is genuinely sincere, heaven itself responds with increase that cannot be prevented by any force. The person who truly sacrifices with sincerity receives back more than they gave — and this return is as inevitable as the rising of the sun.
弗損益之，無咎，貞吉，利有攸往，得臣無家
If one is increased without depriving others, there is no blame. Perseverance brings good fortune. It furthers one to undertake something. One obtains servants but no longer has a separate home.
The ultimate resolution of decrease. 弗損益之 — "not decreasing, but increasing". At the top of the hexagram, the cycle turns: the person has decreased sincerely for so long that now increase comes naturally without requiring anyone else's decrease. This is the miracle of true generosity: it creates increase that does not come at anyone's expense. 得臣無家 — "gains servants but no longer has a separate home". 臣 (chén) is servants, followers; 家 (jiā) is home, family, private household. The person has transcended the private sphere — they no longer operate from a position of private interest but from universal service. Their "home" is the whole community; their "servants" are all who benefit from their selfless action. The teaching: the final fruit of sincere decrease is the disappearance of the separate self. When you have given away enough of your private ego, what remains is a person who belongs to everyone and whom everyone serves.
💡 The Paradox of Decrease: Sǔn's six lines reveal the I Ching's most counterintuitive teaching: decrease IS increase. The progression: measured sacrifice helps others (初九) → maintaining strength serves better than diminishing it (九二) → simplifying relationships finds the right partner (六三) → decreasing faults attracts joy (六四) → heaven responds to sincerity with irresistible increase (六五) → true decrease dissolves the boundary between self and other (上九). The key that runs through all six lines: sincerity (孚). Without sincerity, decrease is mere loss. With sincerity, decrease becomes the most powerful form of increase. The "two small bowls" of the judgment capture this perfectly: when the heart is genuine, even the smallest offering becomes the supreme sacrifice.
The Great Image (大象)
"山下有澤，損。君子以懲忿窒慾。"
"At the foot of the mountain, the lake: the image of Decrease. Thus the superior man controls his anger and restrains his instincts."
山下有澤 (shān xià yǒu zé) — "Below the mountain there is a lake." The lake's waters evaporate and rise to nourish the mountain above. The lake decreases itself to give to something higher — a natural image of willing sacrifice.
懲忿窒慾 (chéng fèn zhì yù) — "Restrains anger and blocks desire." 懲 (chéng) is to restrain, to discipline, to punish; 忿 (fèn) is anger, wrath, fury; 窒 (zhì) is to block, to stop up, to suffocate; 慾 (yù) is desire, lust, craving. The Great Image specifies exactly what should be decreased: not possessions, not wealth, not external things — but anger and desire. These are the two internal excesses that the superior person must sacrifice. 懲忿 — restrain anger: not suppress it but discipline it, reduce it to appropriate levels. 窒慾 — block desire: not eliminate all desire but stop up the excessive, uncontrolled cravings that consume inner resources. The teaching: the most valuable decrease is internal — reducing anger and desire frees the energy that fuels genuine virtue.
Modern Application
💼 Career
Sǔn in career indicates a period where professional reduction serves advancement — accepting a smaller role, reducing ego, simplifying methods. The judgment's "two small bowls" teaches: during decrease, modest but sincere work outperforms flashy but hollow performance. Line 2's paradox is key: sometimes maintaining your own strength helps your team more than sacrificing yourself. Line 5 promises: sincere professional sacrifice is always rewarded, often from unexpected directions. The Great Image: control anger and restrain ambition — these internal decreases enable external advancement.
💰 Business
In business, Sǔn speaks to cost reduction, simplification, strategic downsizing, and the power of doing more with less. The "two small bowls" principle is transformative: in times of decrease, a minimal but sincere product outperforms an expensive but mediocre one. Line 3's teaching applies to partnerships: "three walk together, one is lost" — simplify your stakeholder structure. Line 5: businesses that decrease sincerely (cut waste, not quality) receive market rewards that "cannot be opposed."
❤️ Relationships
Sǔn in relationships teaches that reducing ego, demands, and expectations can transform a struggling relationship. Line 3's "three walk together, one is lost" addresses love triangles and the instability of three-person dynamics. Line 4 is profoundly healing: "decrease your illness" — working on your own faults attracts your partner's joyful return. The Great Image: restraining anger and desire is the most powerful act of love — more powerful than any grand gesture or expensive gift.
🧘 Personal Growth
Sǔn's deepest teaching for personal growth is the Great Image's 懲忿窒慾 — "restrain anger and block desire." These are the two internal excesses that consume the most energy and create the most suffering. The hexagram teaches that decrease is not deprivation but liberation — releasing anger frees emotional energy; blocking excessive desire frees attentional energy. Line 4's "decrease your illness" is a complete self-cultivation program: identify your faults and systematically reduce them. The result: others "hasten with joy." The "two small bowls" is a spiritual teaching: in practice, sincerity matters infinitely more than form; a genuine five-minute meditation outweighs an insincere hour-long ritual.
