Hexagram 16 · Enthusiasm (豫 Yù)

By the Tao Arcana editors · for reflection, not fortune-telling

Enthusiasm is the hexagram of rising energy and shared inspiration, the moment when something stirs that gets people moving together. Thunder bursts up out of the earth, the first crack of a storm releasing the tension that has built up below. A single strong line sits among the yielding ones like the spark that sets a crowd in motion. This is contagious momentum, the kind that, used well, can set great things going.

Thunder sits above, movement and arousal; Earth sits below, the ground that responds. The image of music runs through the commentary, which talks about honouring the rhythm of life and what moves the heart. Enthusiasm here is not idle excitement; it is energy rooted in something genuinely right, which is what lets it rally others rather than just fizzing out. The book also stresses preparation: when you are ready in advance, the moment carries you.

What this hexagram counsels in a reading

When Yu answers your question, energy and momentum are on your side, and the counsel is to put them to work. Inspire others toward a worthy aim. Channel the rising mood into purposeful movement rather than letting it scatter. Crucially, the hexagram pairs enthusiasm with readiness: prepare before you act, so that when the wave comes you can ride it. Excitement without grounding burns out fast, but excitement rooted in real purpose and good preparation can move a great deal.

In love and relationships

For relationships, Enthusiasm points to joy, attraction, and the kind of shared excitement that draws people together and lifts a connection. It is a warm, energising sign. The counsel is to let genuine enthusiasm show and to share it, while keeping it grounded in something real rather than fleeting infatuation. The energy is wonderful for getting things started and for renewing a bond, as long as it rests on more than just the thrill of the moment.

In work and money

In work, Yu favours launching, rallying a team, and harnessing collective momentum behind a project people can believe in. Prepare your ground, then let the enthusiasm carry it forward. With money, it can mark a surge of opportunity and energy, but it gently reminds you to be ready and grounded rather than swept up; channel the excitement into well-prepared action rather than impulse.

Moving lines and the changing hexagram

The moving lines of Enthusiasm range from the warning against enthusiasm that only boasts, to firmness that knows things before they happen, to enthusiasm that deludes itself, to the great source of confidence that rallies friends. A changing line here usually comments on whether your enthusiasm is grounded or hollow. Read it as a check on the quality and direction of your energy. The hexagram it becomes shows where the rising momentum is taking the situation.

Four lines say the hexagram’s own name. The one good line does not.

Yu is unusual in how it is written. Four of its six lines put the hexagram’s name in second position behind a single qualifying character, so what you get is not six situations but four grades of the same one.

Take the four qualifiers on their own. 鳴 is to sound — the cry of a bird, the note of a bell, something making itself heard. 盱 is to open the eyes wide and look up, the face of somebody watching a person above them. 由 is the preposition for by way of, from, through. 冥 is dark, unlit, unseeing.

Now the rulings, in the same order: misfortune, regret twice over, great gains, no blame. The two that fail are the two that involve an audience. Enthusiasm that broadcasts itself gets the blunt 凶 at the bottom of the figure. Enthusiasm with its eyes fixed upward gets regret, and then gets it again for being slow about it. The one that pays is the one with no spectator in it at all — 由豫, the state passing through a person rather than being performed by one. It is also the single strong line in the figure, the one unbroken row in the glyph at the top of this page.

Which leaves the two lines that never use the word:

The second line is the only 吉 in the hexagram, and it belongs to somebody leaving early. 介 carries the sense of a boundary, of being set apart and unmoving; 于石 puts that hardness in stone. Then 不終日 — he does not see the day out. In the hexagram of rising collective mood, the one clearly good outcome goes to the person who is hard to move and does not stay for the whole thing.

The fifth is stranger and gets no ruling at all. A sickness that persists, and does not kill. The ruler’s seat in a hexagram of high spirits is occupied by a chronic complaint that neither clears up nor finishes anybody off.

It is worth noting where the hexagram does approve of sound. The Image assigns Yu to the former kings, who 作樂崇德 — made music and exalted virtue — and offered it to the high god with the ancestors ranged alongside. Music, in that sentence, is sound that has been given a form and pointed at something outside the person making it. The line punished at the bottom of this figure is the one that simply makes a noise.

Line and Image texts follow the copy at Chinese Wikisource, which prints the hexagram in traditional characters. The English is a plain rendering kept close to the Chinese. 朋盍簪 at the end of the fourth line is one of the most obscure phrases in the book — 簪 is a hairpin, and published versions read the clause as friends gathering the way a pin gathers hair, as friends coming quickly, and as a corrupt graph for something else entirely — so it is left at “friends gather” above rather than resolved. 盱 is also read as anxious or as a place name by a minority of commentators.

Its Tarot kin

On the deck side of this site, Enthusiasm rhymes with Wheel of Fortune. Both are about energy in motion, a turning, a momentum that sweeps a situation forward. The Wheel is the great turn of fortune and timing; Yu is that same surge of movement, the thunder that breaks loose and carries everything with it.
