Gathering Momentum

Trigrams:Upper Wind · penetratesLower Thunder · moves

Reading it as a decision

Wind sits above thunder here, and the two reinforce each other — wind fans the thunderclap, thunder gives the wind something to carry. The classical judgment reads plainly favorable: good to move forward, good even to cross a great river, the kind of language reserved for conditions with real backing behind them. Structurally, it's the mirror of the hexagram before it: instead of the lower position giving up ground to the upper, here the upper gives down to the lower, and support flows toward wherever the actual momentum already is.

As a decision-facing signal, this is ground worth holding rather than a cue to jump elsewhere — the read favors staying in a spot where reinforcement is already flowing toward you. When an opportunity, an offer of help, or a partner's momentum lines up with what you're already doing, the guidance leans toward accepting it and moving rather than hesitating out of caution. Classical line texts here run a genuine mix of favorable and mixed signals, less a warning than a reminder to take the help that's offered instead of waiting for a cleaner one.

The classical text

The six lines (爻辭)

  • 初九:利用為大作,元吉,無咎。

    A good time to launch a great undertaking; great fortune, no blame.

  • 六二:或益之,十朋之龜弗克違,永貞吉。王用享于帝,吉。

    Someone adds to it — a precious tortoise-shell worth ten strings cannot be refused; lasting steadiness brings fortune, like a king's offering to heaven.

  • 六三:益之用凶事,無咎。有孚中行,告公用圭。

    Using the increase to meet a crisis brings no blame; sincere and balanced, one reports to the lord bearing a jade tablet.

  • 六四:中行,告公從,利用為依遷國。

    Walking a balanced course, one reports to the lord who agrees, and even the capital may be moved.

  • 九五:有孚惠心,勿問元吉。有孚惠我德。

    A sincere, generous heart brings great fortune without needing to ask; others feel grateful for such kindness.

  • 上九:莫益之,或擊之,立心勿恆,凶。

    No one helps him now, someone even strikes him; an unsteady heart brings misfortune.
