What is Phong Loi Ich in the 64 I Ching hexagrams?
Phong Loi Ich (Chinese characters 風雷益, also called Ich) is hexagram 42 of the 64 I Ching hexagrams, in the King Wen sequence. The hexagram has Ton (巽, symbolizing wind, symbolizing entering) as the outer trigram above and Chan (震, symbolizing thunder, symbolizing movement) as the inner trigram below. Structurally, the hexagram has two yang lines and four yin lines alternating. Its Five Elements phase is Wood. In the 64-hexagram system, it stands right after Son Trach Ton (hexagram 41), and Ton is the opposite (inverse) hexagram of Ich.
The name Ich (益) means to add, to benefit, to increase. Both the hexagram name and its core spirit revolve around one idea: reduce the top to add to the bottom, give in the right place so both sides grow, in the interpretation of Horos.
Why does Phong Loi Ich follow Son Trach Ton?
The Sequence of Hexagrams (Tu Quai) arranges the hexagrams by the causal logic of things. Hexagram 41 is Son Trach Ton, meaning reduce, decrease, harm. After reduction there must come a time of addition, so Ich follows. The common explanation among I Ching researchers is: when loss ends, benefit comes; when reduction ends, addition comes; the two hexagrams form a yin-yang symmetrical pair. Ton reduces the bottom to add to the top; Ich reduces the top to add to the bottom. This is the law of balance that the I Ching stresses many times: when one side has been taken from too much, it is time to give back to the side that lacks.
What does the Judgment of Phong Loi Ich say?
Original Chinese: 益:利有攸往,利涉大川. Sino-Vietnamese reading: Ich: Loi huu du vang, loi thiep dai xuyen.
Meaning: Ich means having somewhere to go is beneficial, crossing the great river is beneficial. In Horos's interpretation, the Judgment of Ich is rarely this clearly favorable, because it encourages both going forward and overcoming difficulties. The time of Ich is a time of being added to, having support, having conditions, so do not stand still. This is the time to start things, take responsibility, do great work. To be given an opportunity and not use it is to waste what was given.
Note: the Judgment does not say "greatly auspicious" or "nothing unfavorable". It states only two specific conditions: beneficial when going forward and beneficial when crossing the great river. This is advice on action, not a guarantee of results.
What does the Image of Phong Loi Ich teach?
Original Chinese: 風雷,益;君子以見善則遷,有過則改. Sino-Vietnamese reading: Phong loi, Ich; quan tu di kien thien tac thien, huu qua tac cai.
Meaning: wind and thunder together are the image of Ich. The junzi follows this: seeing good, he follows it; having faults, he corrects them. Wind and thunder support each other: wind strengthens thunder, thunder speeds wind. The image speaks of self-benefit, that is, a person adding to himself. Seeing others do well, learn without delay; recognizing one's own error, correct without hiding. This is the way to truly grow, in Horos's explanation.
A notable point is that the Image of Ich does not speak of money or external opportunities, but turns inward to self-cultivation. The greatest "benefit" according to the hexagram image is not in what one receives, but in correcting oneself each day.
The six line texts of Phong Loi Ich and plain-language explanations
Below are the original six line texts with Sino-Vietnamese readings and explanations in Horos's presentation. The six lines describe six situations of a person being added to, helped, given opportunity, and how to use what is received correctly.

First line (Sơ cuu, line 1): use what is received for great work
Original: 利用為大作,元吉,無咎. Sino-Vietnamese: Loi dung vi dai tac, nguyen cat, vo cuu. Meaning: beneficial to use for great work, greatly auspicious, no harm.
This is a person newly given extra resources: new investment capital, a large project assigned, financial support from family to start a business, or an opportunity arriving at the right time. The line says clearly: beneficial to use what is received for great work. Do not spend what is received on trivial things, do not hoard in fear of losing it. When momentum exists, use it for worthy work. A person in this line who acts correctly gets very good results.
Second line (Luc nhi, line 2): ten pairs of precious turtle shells come on their own
Original: 或益之十朋之龜,弗克違,永貞吉。王用享于帝,吉. Sino-Vietnamese: Hoac ich chi thap bang chi quy, phat khac vi, vinh trinh cat. Vuong dung huong vu de, cat. Meaning: someone brings ten pairs of precious turtle shells to add, cannot refuse, holding firm long-term is good. The king uses them to sacrifice to heaven, good.
This line's ancient image is very beautiful: someone brings ten pairs of precious turtles to gift, and they cannot be refused. Today, this is being offered unexpected help from a reputable person, a large client seeking you out, a valuable collaboration invitation. The line advises: accept, but hold firmly to your own way afterward. What is received is not yours, but heaven's gift for you to do right work. Only holding it long-term is good.
Third line (Luc tam, line 3): use what is received for difficult matters
Original: 益之用凶事,無咎。有孚中行,告公用圭. Sino-Vietnamese: Ich chi dung hung su, vo cuu. Huu phu trung hanh, cao cong dung khue. Meaning: adding to use for unfortunate matters, no harm. Having sincerity and keeping the middle way, report to the lord holding a jade tablet.
This line uses what is received to fix misfortune: accidents, crises, sudden difficulties in family or work. The line says: no harm, as long as there is sincerity and the middle way is kept. Many people have money, have opportunities come, yet think only of enjoyment. A mature person knows to use what is received at the most needed moment, even when that is a difficult matter. Doing this, one can report to superiors with a clear heart.
The detail "cao cong dung khue" (report to the lord holding a jade tablet) is an ancient ritual, when envoys or subjects held a jade tablet to present matters to rulers. This is the historical context of the Zhou era, not advice for today's reader.
Fourth line (Luc tu, line 4): can move a whole state
Original: 中行,告公從。利用為依遷國. Sino-Vietnamese: Trung hanh, cao cong tong. Loi dung vi y thien quoc. Meaning: keeping the middle way and going, reporting to the lord he follows. Beneficial for relying on to move the state.
This line speaks of the greatest matter in the hexagram: changing the whole direction, moving the whole organization, relocating the whole base. A person in this role already has enough power, enough authority, enough followers to do so. But the line stresses one word: keep the middle way. Having the strength to change the whole situation yet still keeping balance, not extreme, not hasty. Reporting clearly to superiors, they support. This is the most beautiful stage for one in a leadership position.
Fifth line (Cuu ngu, line 5): sincere kindness of heart
Original: 有孚惠心,勿問元吉。有孚惠我德. Sino-Vietnamese: Huu phu hue tam, vat van nguyen cat. Huu phu hue nga duc. Meaning: having sincere kindness of heart, without asking it is greatly auspicious. Having sincerity will kindly treat my virtue.
This is the ruling line of the hexagram. A person here has a sincere heart, intends kindness to those below, does not wait for anyone to ask before giving. The line says: without asking it is greatly auspicious. In return, those below also have sincerity toward one's virtue. Giving and receiving become a natural cycle, without calculation. This is the highest state of Ich: giving not to receive back, but giving rightly naturally brings response.
Top line (Thuong cuu, line 6): no one adds anymore, some even strike
Original: 莫益之,或擊之。立心勿恆,凶. Sino-Vietnamese: Mac ich chi, hoac kich chi. Lap tam vat hang, hung. Meaning: no one adds anymore, some even strike. Keeping a heart that is not constant, bad.
This is the reverse side of the hexagram. A person who has received much, but whose heart is not constant, only wants to receive more without giving. The phrase "lap tam vat hang" in the original means the heart cannot keep the way long-term. At first people still help, later no one helps, and some even turn to strike. The I Ching warns clearly: bad. Receiving endlessly without knowing how to give back, without knowing how to fulfill one's part, then even precious people leave.
How does Phong Loi Ich differ from Son Loi Di?
Many people confuse Phong Loi Ich with Son Loi Di because both have the inner trigram Chan. The key distinction lies in the outer trigram. For Phong Loi Ich, the outer trigram is Ton, that is wind, expressing spreading, diffusion, fitting expansion and development. For Son Loi Di, the outer trigram is Can, that is mountain, expressing condensation, accumulation, fitting preparation and rest.
When predicting travel, the ancients advised: encountering Di, one should postpone if not well prepared. Conversely, encountering Ich, one can set out at once, because wind will push the boat. This distinction is recorded in hexagram analysis documents, showing that just changing the outer trigram, with the same inner trigram Chan, can lead to completely opposite meanings.

How does Phong Loi Ich apply to love, career, wealth, and health?
In Horos's interpretation, Phong Loi Ich cast in life areas usually carries the general message of a time of being added to, but each area has its own shade.
In love, the hexagram often signals a period of addition to the relationship: two people helping each other grow, or a trustworthy third person supporting the couple's love, for example family approval, friends' support, favorable external conditions. This is a favorable time to take a step further such as meeting the family, marriage, living together. But the hexagram has a reminder in line 6: if one side only receives without giving, the relationship will weaken long-term.
In career, the hexagram leans toward a time of being given extra opportunity: assigned an important project, promoted, an investor funding, a large client seeking you out. This is the time to use what is received for great work as line 1 advises, not a time to enjoy. Two things to remember: receiving must be answered, and do not let the desire to receive overwhelm the spirit of giving. Line 5 gives the best advice: kindly treat collaborators, employees, partners, then naturally everything goes smoothly.
In wealth, the hexagram is seen as a hexagram of steady and timely money coming in: salary increase, profitable projects, investment returns, or unexpected support. The hexagram's consistent advice is to use what is gained for worthy things, neither spend wastefully nor hoard selfishly. Line 6 warns directly: whoever only gathers without knowing how to share, when hard times return, no one is beside them.
In health, the hexagram often reminds of a period when the body is recovering and absorbing well: good appetite, deep sleep, effective training. This is a favorable time to build a health foundation for a long cycle ahead. But be careful with over-supplementation: excess vitamins are as harmful as deficiency, overtraining collapses like laziness. These are reference suggestions from hexagram tradition, not medical diagnosis and not a substitute for a doctor's advice.
Which line texts carry social norms of ancient times?
Some details in the six line texts of Ich are tied to rituals and social norms of the Zhou era, to be read as historical context rather than advice applicable today. For example, the third line has the detail "cao cong dung khue", that is, report to the lord holding a jade tablet. This is an ancient court audience ritual, when a subject or envoy held a jade tablet to present matters to rulers. Modern readers can understand the general spirit as presenting transparently to superiors, without needing to repeat the ritual of holding jade. Similarly, the detail "vuong dung huong vu de" in the second line is the scene of a king sacrificing to heaven, belonging to ancient belief context, not practical advice on sacrifice for people today.
Phong Loi Ich in the eight palaces system and Five Elements
According to the book Tuyen tap bai viet Kinh Dich chon loc so 1, Phong Loi Ich belongs to the Ton palace (phase Yin Wood), in the same group as hexagrams such as Bat Thuan Ton, Phong Thien Tieu Suc, Phong Hoa Gia Nhan, Thien Loi Vo Vong, Hoa Loi Phe Hap, Son Loi Di, Son Phong Co. The Ton palace represents Phong (wind), phase Yin Wood, located in the Southeast. When analyzing the 64 hexagrams by Wood phase, we see growth, development, and intense vitality, matching the spirit of expansion, diffusion, and benefiting of Ich.
In the hexagram lookup table of Khong Minh Than Toan, Phong Loi Ich also appears at the junction of inner trigram Chan and outer trigram Ton, confirming the structure of wind above thunder below. However, a clear distinction is needed: the verse cards in Khong Minh Than Toan are card texts of a separate divination system, not the line texts of Zhou Yi, so when looking up Ich according to Zhou Yi, only use the Judgment, Image, and six line texts of the I Ching, without mixing in Khong Minh card texts.
Main lesson of Phong Loi Ich
The core spirit of Phong Loi Ich lies in the idea of reducing the top to add to the bottom. When one has conditions, support, opportunity, one easily thinks of keeping for oneself. Ich goes against that reflex: what is given must be used for worthy work, and one in a higher position must know to share with the lower so the whole system grows together.
The Image opens another layer of meaning: "seeing good, follow it; having faults, correct them". This is the way to add to oneself without anyone granting it. Among the six lines, lines 1 to 5 all describe favorable situations accompanied by specific responsibilities, while line 6 is a warning for one who receives endlessly without knowing how to give. Reading the whole hexagram, the message is not "casting this hexagram means joy", but "this time adds to us, so what do we use that addition for and to whom do we give back".
It must be stressed that the I Ching is a system of philosophy and contemplation, not a tool of certain prediction. All hexagram readings should be read only as suggestions for reflection, not a substitute for practical decisions based on each person's specific data.
