🧭 Trigram Architecture & Four-Hexagram Transformation Graph

At UK MASTER ACADEMY, no hexagram is read in isolation. Classical Chu Yi analysis situates Following within its Upper-Lower trigram dynamic alongside three structural counterparts: the Nuclear Hexagram (hidden internal progression), the Opposite Hexagram (complete Yin-Yang polarity inversion), and the Inverse Hexagram (180-degree perspective reversal):

📐 Na Jia Six-Line Matrix (Wen Wang Gua / Six Lines System)

Whenever a Six-Relative is absent from the primary six lines, its Hidden God (Fu Shen) is drawn from the pure Palace Head hexagram:

📊 Line-by-Line Commentary: All 6 Moving Lines & Transformations

Counted from the bottom upward (Initial, Second, Third, Fourth, Fifth, and Top), the six lines trace the complete arc of an affair from inception to culmination. When casting with our Three-Coin I Ching Tool or Plum Blossom Divination Calculator, focus on the moving line(s) alongside the resulting Transformed Hexagram:

Line 1 · Nine at the Beginning Yang Line · Parents (Fu Mu) · Water Changes to Hexagram 45: Cui
Line Text: Office and duty may change; hold to what is correct and it is auspicious. Go out of the gate and mix with others, and there will surely be merit.\n
Lesser Image: To change and yet follow what is correct is auspicious; to go out and mix with others loses nothing.\n

Master Ưng Khiêm's Commentary: You are at a moment when you must let go of the old in order to follow the new, and this is not disloyalty but knowing how to move with the time. I have seen that this line advises you not to close yourself off, but to widen your circle boldly, for a person newly met may prove to be a benefactor. What matters above all is keeping an upright heart while you change, and never surrendering your principles for a gain that lies close at hand.\n

When Line 1 Moves in Divination: Wealth: fortune comes through new relationships, so take the initiative in making connections. Work: a change of direction or of partner is favourable if you hold to the right path. Love: you meet someone outside your old familiar circle, so be open. Health: changing an old way of living is also something worth doing now. Decisions: dare to step outside your safe ground.\n
Strategic Counsel: Go out and widen your circle, but remember to keep an upright heart as your root while you move with the time.
Line 2 · Six in the Second Place Yin Line · Siblings (Xiong Di) · Wood Changes to Hexagram 58: Dui
Line Text: Bind yourself to the lesser one and you lose the man of stature worth following.\n
Lesser Image: Once bound to the lesser one, you cannot also hold to the one worth following.\n

Master Ưng Khiêm's Commentary: This line warns you about a divided heart. Standing between a small gain close at hand and a great support that would last, you cannot keep both. I have seen many people caught by a small profit and so miss the true benefactor. This is a time to look again with a clear head and ask who really deserves to be the one you lean on for the long road.\n

When Line 2 Moves in Divination: Wealth: beware of coveting a small gain and losing the large one. Work: do not scatter your strength on side matters; concentrate on the main thing. Love: you may waver between two people, and you must choose decisively or a good match will pass you by. Health: do not chase a small pleasure at the cost of your health in the long run. Decisions: settle what your real priority is before you act.\n
Strategic Counsel: Look further than the gain in front of you, and choose the right person and the right work to bind yourself to for the long term.
Line 3 · Six in the Third Place Yin Line · Wife and Wealth (Qi Cai) · Earth · World Line Changes to Hexagram 49: Ge
Line Text: Follow the man of stature and you let the lesser one go. Following, what you seek you will obtain; it is favourable to dwell in what is correct.\n
Lesser Image: To follow the man of stature is the will that knows how to give up what is base.\n

Master Ưng Khiêm's Commentary: This line carries on the thread of the second. Once you have decisively let the small go in order to follow the great, the road ahead grows clearer. I lay stress here on the word perseverance, which means that even when you have chosen the right direction you must still keep yourself upright, and never use a new position to do what is wrong. Only so will what you hope for prove truly lasting.\n

When Line 3 Moves in Divination: Wealth: cut off the small gain and follow the larger direction, and your wish will be met. Work: moving to a better environment is the right choice, so hold steady. Love: break cleanly with a bond unworthy of you and go to the person of greater worth. Health: give up a bad habit and take up a wholesome way of living. Decisions: keep an upright heart now that you have chosen a new direction.\n
Strategic Counsel: Let go of the small decisively in order to follow the great, but always keep the right path as the ground beneath every step.
Line 4 · Nine in the Fourth Place Yang Line · Parents (Fu Mu) · Water Changes to Hexagram 03: Zhun
Line Text: To be followed and so to gain: hold to this forever and there is misfortune. Keep sincerity within the right principle, act with clear discernment, and where then is the fault?\n
Lesser Image: To be followed and so to gain is, in point of principle, a thing to be uneasy about. To keep sincerity in accord with principle is the merit of clear discernment.\n

Master Ưng Khiêm's Commentary: This line falls in the place next to the ruler. It has standing, and many people submit to it, yet it is exactly this popularity that easily breeds suspicion from above. I advise you that when you hold a position many people support, you must be all the more transparent, keep your sincerity toward your superiors and toward the right path, and not let that soft power become a blade with two edges.\n

When Line 4 Moves in Divination: Wealth: there is a harvest, but its source must be transparent; avoid anything murky. Work: you are trusted and yet easily suspected, so let your work be plain and open. Love: you are admired by many, and your fidelity must be visible and clear. Health: do not hide an illness; be open with your doctor so that the treatment is right. Decisions: keep everything open and above board so that no suspicion can settle.\n
Strategic Counsel: To win the hearts of people is a blessing and also a danger; keep your sincerity and your transparency, and every suspicion will dissolve.
Line 5 · Nine in the Fifth Place Yang Line · Officer and Ghost (Guan Gui) · Metal Changes to Hexagram 51: Zhen
Line Text: To trust in what is good and follow it, auspicious.\n
Lesser Image: To trust in what is good and so be auspicious, because the place is correct and central.\n

Master Ưng Khiêm's Commentary: This is the fine line of the hexagram Sui (Following): a person in a high seat, in the correct place, who knows how to trust and to follow what is good and worthy. I have seen that this line teaches us a great lesson, that a good leader is not the one who imposes but the one who listens, who can follow the good in those below and in the circumstances themselves. When trust is placed where it belongs, blessing arrives of its own accord.\n

When Line 5 Moves in Divination: Wealth: trust the right person and the right undertaking, and money flows smoothly. Work: your superiors trust you, or you yourself know how to employ able people; this is greatly auspicious. Love: a bond built on sincere trust, and very durable. Health: follow the sound advice of a good physician. Decisions: decide by trusting in what is good, and the result will be fortunate.\n
Strategic Counsel: Hold to the central and the correct, know how to trust and to follow what is good, and blessing will surely come to you.
Line 6 · Six at the Top Yin Line · Wife and Wealth (Qi Cai) · Earth · Response Line Changes to Hexagram 25: Wu Wang
Line Text: Bind him fast, and then bind him yet more firmly. The king uses this to make offering on the Western Mountain.\n
Lesser Image: Bound as fast as this, the way of following has reached its utmost.\n

Master Ưng Khiêm's Commentary: At the last line, loyalty in following the way has grown so firm that nothing can shake it, as though one were bound a second time to make it firmer still. I explain the old story of King Wen, who used such sincerity to make offering on the Western Mountain: the meaning is that when the hearts of people have submitted utterly, great matters and sacred matters alike can be brought to completion. This is the line of a faith that has ripened.\n

When Line 6 Moves in Divination: Wealth: the foundation is solid and prosperity will last. Work: you are entrusted with a weighty task, so receive it with gratitude. Love: the bond is firm, and you may think about the long term. Health: a wholesome way of living has become a settled habit. Decisions: the moment is ripe for great matters and for matters of weight.\n
Strategic Counsel: Your sincerity has ripened; use it now for great work and for sacred work, and the result will be complete.

🌟 Practical Divination Across Major Life Domains

Overall strategic trajectory of Hexagram 17 Following · UK MASTER ACADEMY

1. Overall Trajectory & Strategic Timing

Lake above and Thunder below, thunder sinking into the lake to rest. This is the image of following, of going along with the times. Know how to adapt and stay flexible, and there is success. Because Dui (Lake) (Metal) rides above Zhen (Thunder) (Wood), the hexagram asks you to align inner preparation (arousing movement, awakening, decisive action) with outward execution (joyous exchange, eloquence, harmonious communication).

Core Decision Principle: Thunder within the lake; the noble one goes indoors at nightfall to rest. At the ruler's fifth position, classical guidance emphasizes: decide by trusting in what is good, and the result will be fortunate.

2. Career, Leadership & Financial Strategy

Career & Governance: In the opening phase (Line 1), the counsel for work is clear: a change of direction or of partner is favourable if you hold to the right path. As the hexagram matures to its fifth position (Line 5), leadership reaches its decisive test: your superiors trust you, or you yourself know how to employ able people; this is greatly auspicious. Anchor your authority on the World Line (Line 3) while observing how counterparts respond at Line 6.

Wealth & Capital Allocation: Early financial posture requires discipline: fortune comes through new relationships, so take the initiative in making connections. When conditions ripen at the fifth line, capital movement shifts: trust the right person and the right undertaking, and money flows smoothly. In Six Lines casting, examine the Wife and Wealth (Qi Cai) line within the Zhen Palace table above to judge liquidity and timing.

3. Relationships, Marriage & Family Harmony

Relational harmony depends on the resonance between the Inner Trigram (Zhen (Thunder), self/home) and Outer Trigram (Dui (Lake), partner/environment). In the developing inner stage (Line 2), relationship dynamics indicate: you may waver between two people, and you must choose decisively or a good match will pass you by. At maturity (Line 5), the bond reflects: a bond built on sincere trust, and very durable.

Remember to cross-check the Nuclear Hexagram (Hexagram 53: Development) when unspoken emotional expectations or family pressures sit beneath the surface.

4. Health, Constitutional Qi & Medical I Ching

In classical Medical Yi (Yi Yi), Dui (Lake) corresponds to the mouth, tongue, teeth, bronchi, respiratory mucosa, whereas Zhen (Thunder) governs the feet, liver, gallbladder, sinews, nervous reflexes. Early moving-line diagnostics note: changing an old way of living is also something worth doing now. At the uppermost extreme (Line 6), guard against overextension: a wholesome way of living has become a settled habit.
