Judgment

Legge: Compensating Sacrifice means that sincerely maintained rectitude brings great success. Action is appropriate if one's sacrifice is sincere -- even two baskets of grain, though there be nothing else, may be offered.

Wilhelm/Baynes: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? One may use two small bowls for the sacrifice.

Blofeld: Loss accompanied by confidence -- sublime good fortune and no error! It is favorable to have in view some goal (or destination). If there is doubt as to what to use for the sacrifice, two small bowls will suffice.

Liu:Decrease with sincerity: great good fortune, no blame. One may continue. It is beneficial to go somewhere. How can this (decrease with sincerity) be done? One may use two bamboo containers of grain for a sacrifice.

Ritsema/Karcher: Diminishing, possessing conformity. Spring significant. Without fault, permitting Trial. Harvesting: possessing directed going. Asking-why: having availing of. Two platters permit availing-of presenting. [This hexagram describes your situation in terms of sacrifice and loss. It emphasizes that lessening yourself and decreasing your involvements is the adequate way to handle it...]

Shaughnessy: There is a return; prime auspiciousness; there is no trouble. It can be determined. Beneficial to have someplace to go. Why use two tureens; you can use aromatic grass.

Cleary (1): Reduction with sincerity is very auspicious, impeccable. It should be correct. It is beneficial to go somewhere. What is the use of the two bowls? They can be used to receive.

Cleary (2): … It is beneficial to have somewhere to go, etc … They can be used for presentation.

Wu: Loss indicates that with confidence there will be great fortune, no error, perseverance, and advantage to have undertakings. What to use in offerings? Two boxes of grain are adequate.

 

The Image

Legge: The image of a mountain and beneath it the waters of a marsh form Compensating Sacrifice. The superior man, in accordance with this, restrains his wrath and represses his desires.

Wilhelm/Baynes: At the foot of the mountain, the lake: the image of Decrease. Thus the superior man controls his anger and restrains his instincts.

Blofeld: This hexagram symbolizes a marshy lake at the foot of a mountain. The Superior Man keeps his anger under control and is moderate in his desires.

Liu: The lake beside the mountain symbolizes Decrease. The superior man curbs his indignation and restricts his desires.

Ritsema/Karcher: Below mountain possessing marsh. Diminishing. A chun tzu uses curbing anger to block the appetites.

Cleary (1): There is a lake under a mountain, reducing it. Thus does the superior person eliminate wrath and cupidity.

Cleary (2): Lake below a mountain – Reducing. Thus do developed people eliminate anger and greed.

Wu: There is a marsh below the mountain; this is Loss. Thus the jun zi mitigates his anger and restrains his desires.

 

COMMENTARY

Confucius/Legge: In Compensating Sacrificethe lower trigram is diminished to increase the upper, and the flow is upward. The two baskets of grain accord with the time. There is a time when the strong should be diminished and the weak strengthened. Decrease and increase, overflowing and emptiness, take place in harmony with the demands of the time.

Legge: Ch'eng-tzu says: "Every diminution and repression of what we have in excess to bring it into accordance with right and reason is comprehended under Compensating Sacrifice. If there is sincerity in doing this it will lead to success and happiness, and even if the offering is small, yet it will be accepted."

The K'ang-hsi editors say: "What is meant by diminishing in this hexagram is the regulation of expenditure or contribution according to the time. This would vary in a family according to its poverty or wealth, and in a state according to the abundance or scantiness of its resources. If one supplements the insufficiency of his offering with the abundance of his sincerity, the insignificance of his two baskets will not be despised."

The waters of a marsh are continually rising up in vapor to bedew the hill above it, and thus increase its verdure. What is taken from the marsh gives increase to the hill.

 

NOTES AND PARAPHRASES

Judgment: A sacrifice creates equilibrium.

The Superior Man sacrifices his appetites to a higher principle.

The traditional name for this hexagram is Decrease, but the lines and commentary all describe a compensating exchange of forces to attain equilibrium. The idea of "sacrifice" is mentioned in the Judgment, and that also might make a good title, though the image of two baskets of grain suggests a balancing scale: a "compensating" device. In this hexagram, the flow of energy moves from below upwards -- the waters of the lake or marsh are dispersed to enrich the mountain. In psychological terms we think of the ego sacrificing or decreasing its autonomy to achieve psychic equilibrium with the Self: we forfeit something valuable to obtain something even more valuable. Without this quid pro quo, the concept of sacrifice is meaningless and irrational.

A sacrifice is meant to be a loss, so that one may be sure that the egoistic claim no longer exists. Therefore the gift should be given as if it were being destroyed. But since the gift represents myself, I have in that case destroyed myself, given myself away without expectation of return. Yet, looked at in another way, this intentional loss is also a gain, for if you can give yourself it proves that you possess yourself. Nobody can give what he has not got.
Jung -- Transformation Symbolism in the Mass

Compare the Image message from hexagram number 15, Temperance with the notion of a compensating balance: "The superior man, in accordance with this, diminishes his excesses to augment his insufficiencies, thus creating a just balance." We are reminded of another "Temperance" -- the 14th Arcanum of the Tarot, which depicts an angel pouring water from one vessel into another: "compensating." A comparison of its symbolism with that of hexagram number 41 yields many insights:

The Path of ... TEMPERANCE, leads from ... the Personality [ego] to the Higher Self ... The whole experience is one of preparation of the Personality [ego], and the body in which it is operating, to deal with an influx of Light which would be devastating to a system unready to handle such energy. Most important here is the monitoring of progress, the continual testing from above. It is the angel here which is at once the Higher Self and the initiatory forces of Nature, which pours the elixir from vase to vase. This is an ongoing process of testing; measuring to see how much the physical vehicle can bear.
R. Wang --The Qabalistic Tarot

Without belaboring the point, we can see that all sacrifice is a kind of remuneration: it couldn't be otherwise in an interconnected universe. The Image instruction for the superior man to “control his anger” is also echoed in the Temperance card. This relates to:

...an aspect of the Mysteries only rarely discussed, and certainly germane to the Twenty-Fifth Path [the Kabbalistic equivalent of the relationship between lines one and four in this hexagram]: this is the very real hostility often felt by the student toward the Path itself, as he works day after day and seems to be getting nowhere. Such hostility and frustration is in itself a major test; it is part and parcel of the work prior to the emergence of inner proofs. -- Ibid

"Decrease with sincerity" (Liu) refers to one's continuous sacrifice for the goals of the Work, and "curbing anger" (Ritsema/Karcher) is how one handles the archetypal forces evoked when the decrease seems endless and you've yet to receive anything in return. Like any other hexagram, Compensating Sacrifice can symbolize an infinity of possible situations, but psychologically speaking we can first regard it as an image of sacrifice for the purpose of attaining a balance of power within the psyche. Without the sacrificial devotion of the ego, the Self cannot attain its will; and if the Self can't make it, the ego is doomed by default.


Line 2

Legge: The second line, dynamic, shows that it will be advantageous for its subject to maintain firm correctness, and that action on his part will be evil. He can give increase to his correlate without taking from himself.

Wilhelm/Baynes: Perseverance furthers. To undertake something brings misfortune. Without decreasing oneself, one is able to bring increase to others.

Blofeld: Persistence in a righteous course brings reward, but to advance (or go anywhere) now would bring misfortune. This is not a time for decreasing but for augmenting.

Liu: To continue is beneficial. Undertakings bring misfortune. Without decrease, without increase.

Ritsema/Karcher: Harvesting Trial. Chastising: pitfall. Nowhere Diminishing, augmenting it.

Shaughnessy: Beneficial to determine; to be upright is inauspicious. Not decreasing it, but increasing it.

Cleary (1): It is beneficial to be correct. An expedition is inauspicious. No reduction or increase of this. [If you do not know when enough is enough and go on reducing and increasing, you will reactivate the human mentality and thus obscure the mind of Tao … It is because the strong energy is balanced, not biased or lopsided, that there is no more reduction or increasing to be done.]

Cleary (2): … Increase it without reduction.

Wu: It is advantageous to be firm and correct, but foreboding to go ahead. His decision of not taking a loss will benefit the other. [It may be justifiable for the below to support the above in a very moderate way in time of Loss, but it would be unacceptable by asking the below to give up all of its possessions … to satisfy the above.]

 

COMMENTARY

Confucius/Legge: His central position gives its character to his aim. Wilhelm/Baynes: It has the correct mean in its mind. Blofeld: The central position of this line in the lower trigram indicates that persistence will be rewarded by the fulfillment of what is willed. Ritsema/Karcher: Centering using activating purposes indeed. Cleary (2): The balance that characterizes its aim. Wu: He is to remain central.

Legge: Line two is dynamic and in the central place. But he is in the place of a magnetic line, and should maintain his position without moving to help his fifth line correlate. Maintaining his own firm correctness is the best way to give assistance. " His aim" is to abide where he is and help the fifth line by the exhibition of firm correctness.

 

NOTES AND PARAPHRASES

Siu: The man renders faithful service without sacrificing himself. Forfeiting one's dignity and personality to do the bidding of a person of high rank is shameful.

Wing: When aiding others, be certain to maintain your sense of dignity. If the nature of your task diminishes your strength or compromises your principles, or if you sacrifice your personality to please your superior, you are acting shamefully. Only efforts that do not diminish your Self are worthwhile.

Editor: This line changes the hexagram to number twenty- seven, Nourishing, the corresponding line of which carries a similar message, i.e., the idea that one's impetus to act is incorrect. Lines one and three each show some variation of active compensating (balancing) going on. Here in line two, which is the center of the lower trigram, action is inappropriate. It is the fulcrum or point of balance which must remain stationary. Note the subtle differences in the various translations of the last sentence. You decide.

The Sage uses his mind like a mirror. It remains in its place passively, and it gives back what it receives without concealment. Therefore it can overcome things without distorting them.
Chuangtse

A. You serve the Work best now by remaining in place. Willpower, non-action and example are all the assistance that is required.

B. Maintain the status-quo.

Line 4

Legge: The fourth line, magnetic, shows its subject diminishing the ailment under which she labors by making the subject of the first line hasten to her help, and make her glad. There will be no error.

Wilhelm/Baynes: If a man decreases his faults, it makes the other hasten to come and rejoice. No blame.

Blofeld: He reduced the number of ills besetting him and thus hastened the arrival of happiness -- no error!

Liu: If he decreases his sickness (or faults) quickly, he will be happy. No blame.

Ritsema/Karcher: Diminishing one's affliction. Commissioning swiftly possesses rejoicing. Without fault.

Shaughnessy: Decreasing his illness; serving ends has happiness; there is no trouble.

Cleary (1): Reducing sickness, causing there to be joy quickly, there is no fault.

Cleary (2): Reducing the ailment causes there to be joy soon. No blame.

Wu: His illness is alleviated and conditions are quickly improved. There is joy. No error.

 

COMMENTARY

Confucius/Legge: This is a matter for joy. Wilhelm/Baynes: It is indeed something that gives cause for joy. Blofeld: A reduction of troubles is in itself a cause for happiness. Ritsema/Karcher: Truly permitting rejoicing indeed. Cleary (2): Reducing the ailment is a matter of joy. Wu: Capable of alleviating his illness is a cause for joy.

Legge: Line four is magnetic in a magnetic place, like someone ailing and unable to perform her proper work. But her first line correlate is strong, and is made to hasten to four's relief. The joy of the line shows her desire to do her part in the work of the hexagram.

 

NOTES AND PARAPHRASES

Siu: As a consequence of giving up his bad habits, the man attracts the help of well-disposed friends.

Wing: If you can now locate your shortcomings and bad habits and make a serious attempt to decrease them you will be approached by friends and helpers. A humble attitude on your part will open the way to progressive interaction and joy.

Editor: The full meaning of this line is best evoked by comparing it with its first line correlate. All translations render line four in the imagery of decreasing one's faults (or illness). That is: rid yourself of error and happiness will come to you. Legge's version depicts incapacity which is overcome through a correct union with line one. Taken in this sense, the line can symbolize the Self (line four, upper trigram of Heaven) gaining from the ego's sacrifice in spacetime (line one, lower trigram of Earth). Whatever the context of your query, the image here is of a harmonization of forces to bring about balance.

Man is a materialized thought; he is what he thinks. To change his nature from the mortal to the immortal state he must cease to hold fast in his thoughts to that which is illusory and perishing, and hold on to that which is eternal.
F. Hartmann --Paracelsus: Life and Prophecies

A. A decrease in error is an increase in truth.

B. The elimination of imbalance promotes union; the elimination of illusion makes room for joy.

C. The one above (the Self) accepts your aid, endorses your action, etc.

Line 6

Legge: The sixth line, dynamic, shows its subject giving increase to others without taking from himself. There will be no error. With firm correctness there will be good fortune. There will be advantage in every movement that shall be made. He will find ministers more than can be counted by their clans.

Wilhelm/Baynes: 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. [Through perseverance and zealous work a man wins success and finds helpers as they are needed. But what he accomplishes is not a limited private advantage; it is a public good and available to everyone… There are loyal helpers, but not for promoting family interests.]

Blofeld: Gain which causes no loss to others involves no error. Persistence in a righteous course brings good fortune. It is favorable to have in view some goal (or destination). He obtains followers but not a family (or home).

Liu: If one increases (gains) without anyone decreasing (losing), no blame. To continue brings good fortune. It is beneficial to go somewhere else; one will find a helper after leaving home.

Ritsema/Karcher: Nowhere Diminishing, augmenting it. Without fault. Trial: significant. Harvesting: possessing directed going. Acquiring a servant, without dwelling.

Shaughnessy: Not decreasing it, but increasing it; there is no trouble; determination is auspicious; there is someplace to go; obtain a servant without family.

Cleary (1): Not reducing or increasing this is faultless. Correctness brings good fortune. It is beneficial to go somewhere. Getting a servant, there is no house. [The mind of Tao is the master, the human mind is the servant. When the mind of Tao is in charge of things, every step, every undertaking, is celestial design; personal desires do not arise, and even the human mind transforms into the mind of Tao: “getting a servant, there is no house” … This is returning to ultimate good by reduction.]

Cleary (2): Increase without reduction, and there will be no blame. Correctness leads to good results. There is somewhere to go. Getting an administrator without a house. [To increase the third yin, it is necessary not to reduce the top yang. This is because the third yin as an administrator is in the position of “losing one’s home in the service of the country,” but the top yang perceives the sincerity of this lone journey, so this is “great attainment of the objective,” and the third yin considers this “getting companionship.” This is called “increase without reduction.”]

Wu: His wishes of not taking a loss will benefit others. No error. Perseverance brings auspiciousness. It is advantageous to have undertakings. His subordinates are so dedicated to their assignments that they act as if they had no families.

 

COMMENTARY

Confucius/Legge: He obtains his wish on a grand scale. Wilhelm/Baynes: He attains his will in great measure. Blofeld: The first sentence presages the complete fulfillment of what is willed. Ritsema/Karcher: The great acquiring purpose indeed. Cleary (2): Increase without reduction is great attainment of the objective. Wu: His aspiration is fully realized.

Legge: Line six has been changed from a magnetic to a dynamic line from line three. He has received the greatest increase and will carry out the idea of the hexagram in the highest degree and style. He can increase others without diminishing his own resources, and the benefit will be incalculable. Ministers will come to serve him, and not one from each clan only, but many. Ch'eng-tzu says on line six: "Dwelling on high and taking nothing from those below him, but on the contrary giving more to them, the superior man accomplishes his aim on a grand scale. The aim of the superior man is simply to be increasing what others have -- that and nothing else.”

 

NOTES AND PARAPHRASES

Siu: The man increases in power and dispenses blessings to the world without diminishing his own resources. Everyone willingly serves him because he does not siphon off resources to his private advantage.

Wing: Expand your goals to encompass a more universal pursuit. In this way others will lend support. Your successes will lead you to a new public awareness. You may find this social position and responsibility a desirable new life-style and a benefit to many.

Editor: There is a conceptual disagreement between Legge's rendition of this line and that of the other translators. Legge: “increasing others while not decreasing oneself.” Wilhelm: “increasing oneself without decreasing others.” Cleary’s Buddhist version is the most neutral: “increase without reduction.” My understanding of the hexagram is that it depicts a process of active compensation -- the continuous give and take of life which maintains a fair equilibrium: neither pole imbalances the other. Psychologically interpreted, the sentence about the “servant but no home,” suggests the creation of a kind of Psychic Commonwealth in which all the complexes have become integrated enough to abandon their partisan interests and serve the intentions of the Self. The ego as an administrator or servant is essential for the attainment of this.

Insofar as analytical treatment makes the “shadow” conscious, it causes a cleavage and a tension of opposites which in their turn seek compensation in unity.
Jung –Memories, Dreams, Reflections

It may be thought that a few initiates living life according to principle could have little effect on the vast mass of people living their lives in various degrees of chaos, seeking only after pleasure and profit rather than principle. The point is, though, that a life lived with talismanic intention has far greater force than one that has its patterns based, not on spiritual reality, but on day to day physical expediency.
Gareth Knight -- Qabalistic Symbolism

A. A harmonious alliance or balance of power is created through the wise apportionment of energy and resources.

B. It costs you nothing to benefit the situation.

C. Increase without decrease.

Shock


Other titles: The Arousing, Thunder, The Symbol of Startling Movement, Shake, The Beginning of Movement, Shocking, The Thunderclap, Action, Motion, Sudden Change, Surprise! "The necessity to keep tranquil in the midst of upheaval." -- D.F. Hook

 

Judgment

Legge:Shock intimates ease and development. When the time of movement which it indicates comes, the subject of the hexagram will be found looking out with apprehension, and yet smiling and talking cheerfully. When the movement like a crash of thunder terrifies all within a hundred miles, he will be like the sincere worshipper who is not startled into dropping his ladle and cup of sacrificial spirits.

Wilhelm/Baynes:Shock brings success. Shock comes --oh, oh! Laughing words -- ha, ha! The shock terrifies for a hundred miles, and he does not let fall the sacrificial spoon and chalice.

Blofeld: Thunder -- success! Thunder comes with a terrible noise, laughing and shouting in awesome glee and frightening people for a hundred miles around. The sacrificial wine is not spilt. [This suggests that the holder of the sacrificial vessel is not easily alarmed or else that he is very wise and able to distinguish between the apparently dangerous and the truly dangerous.]

Liu: Thunder. Success. Thunder comes -- ho ho! Speaking and laughing -- ha ha! It shocks and terrifies for a hundred miles. But one does not drop the spoon or chalice.

Ritsema/Karcher: Shake, Growing. Shake coming: frightening, frightening. Laughing words, shrieking, shrieking. Shake scaring a hundred miles. Not losing the ladle, the libation. [This hexagram describes your situation in terms of a disturbing and inspiring shock. It emphasizes that rousing things to new activity, the action of Shake is the adequate way to handle it. To be in accord with the time, you are told to: stir things up!]

Shaughnessy:Thunder: Receipt; thunder comes so renewingly; laughter and talk yaya; thunder alarms one hundred miles; not losing the ladle or goblet.

Cleary (1): Thunder is developmental. When thunder comes, there is alarm, then laughter. Thunder startles for a hundred miles, but one does not lose the spoon and wine.

Cleary (2):Thunder comes through. Etc.

Wu:Motion indicates pervasiveness. When Motioncomes, it frightens people. Later, it makes people talk and laugh. Its majesty reaches one hundred li in all directions. There is no misplacement of the ladle or sacrificial wine.

 

The Image

Legge: The image of Thunder, being repeated, forms Shock. The superior man, in accordance with this, is fearful and apprehensive, cultivates his virtue, and examines his faults.

Wilhelm/Baynes: Thunder repeated: the image of Shock. Thus in fear and trembling the superior man sets his life in order and examines himself.

Blofeld: This hexagram symbolizes continuous thunder. The Superior Man in fear and trembling seeks to improve himself.

Liu: Thunder doubled symbolizes shock. The superior man contemplates himself with fear and caution.

Ritsema/Karcher: Reiterated thunder. Shake. A chun tzu uses anxious fearing to adjust inspecting.

Cleary (1):Traveling thunder reverberates. Thus superior people cautiously practice introspection.

Cleary (2): Repeated thunder reverberates.Developed people practice introspection with caution.

Wu: One thunderclap after another constitutes hexagram Motion. Thus the jun zi reflects and rectifies for fear of being wrong.

 

COMMENTARY

Confucius/Legge: His feeling of dread leads to happiness because he is thereby made to adopt proper laws for himself. The movement startles the distant and frightens the near, yet he makes the proper sacrifices the same as always.

Legge: Shock consists of the trigram for Thunder doubled. (This trigram also represents Movement and the Eldest Son.) The hexagram therefore symbolizes a crash or peal of thunder, and combined with the idea of movement shows a sudden change taking place in the kingdom. The lesson is the conduct to be pursued in a time of sudden change through an awareness of danger and the proper regulation of oneself.

A successful issue is predicted if the dynamic first line can be superior to the two magnetic lines above him. It is in the idea of the hexagram that he should be moving and advancing. Although sensible of the danger, he is confident and self-possessed -- so much so that he can calmly perform his religious duties during the prevailing chaos. This is proper behavior for the eldest son, who must eventually assume the duties of his father.

Anthony: In the I Chingshock means being subjected to unsettling events. It also means perceiving and reacting to these events … perceiving, in any of these changes, that a new set of limits, or deprivations, has been placed on our life which seems to restrict or even penalize us. This sense of being projected by events into a sort of emotional trap is what this hexagram calls “Fate.” Acknowledgement of this fate, or trap, and the imperative – to find the way out – is one of the purposes of shock. As far as the I Ching is concerned, there is only one way out – to undergo spiritual development.

 

NOTES AND PARAPHRASES

Judgment: During sudden changes, adjust your tempo and move ahead, remembering that while conditions may alter, the goal remains the same.

The Superior Man double-checks his premises, confronts his weak spots and adheres to the rules and ideals of the Work.

The image here is one of a sudden, dramatic release of energy, power and force. To receive this hexagram without changing lines can refer to almost any abrupt, startling or unexpected situation. Sometimes it is the oracle's way of saying: "Surprise!” It can also be a kind of reprimand for asking a dumb or inappropriate question -- the oracle is "shocked” by your temerity, ignorance, etc. In such instances there is often an element of wry humor in the situation -- usually at the ego's expense. On rare occasions, it is possible to receive this hexagram as a warning about an upcoming event which has no bearing on the question posed. Should you receive such an oracle, be extremely vigilant – as always, the advice to the superior man in the Image suggests the proper course.

A true test of devotion to the Work is to maintain one's will under all circumstances. The world may be falling apart around us, but the adept does not ruin the performance of his sacrifice: the ego continues the Work regardless of conditions, and keeps a cool head under all circumstances.

Have no fear of sudden terror

or of assault from wicked men,

since Yahweh will be your guarantor,

He will keep your steps from the snare.

Proverbs 3: 25-26

Both Yahweh and Christ are what Jung calls "god images” which exist in one form or another in every human psyche, whether it is consciously religious or not. The god image is synonymous with the Self, and the implication of the above quotation from Proverbsis that as long as the ego remains devoted to the Work -- in I Chingterms: "maintains the sacrifice” -- it is under the protection of the Self.

The Perfect Man is godlike. Though the great swamps blaze, they cannot burn him; though the great rivers freeze, they cannot chill him; though swift lightning splits the hills and howling gales shake the sea, they cannot frighten him. A man like this rides the clouds and mist, straddles the sun and moon, and wanders beyond the four seas. Even life and death have no effect on him, much less the rules of profit and loss!
Chuang Tzu
