Hexagram 43, Break-through (Guài, 夬), is formed of the upper trigram Lake (兑) over the lower trigram Heaven (乾). Below is the classical judgment, the six line texts, and how to read this hexagram in a reading.
The Judgment
Breakthrough: proclaim it at the king's court; the sincere cry carries danger. Notify your own city first; arms do not further, but going forward does.
扬于王庭，孚号有厉；告自邑，不利即戎，利有攸往。
Trigrams
☱
Upper · Lake 兑
joy, openness
☰
Lower · Heaven 乾
the creative, strength
The outer (upper) trigram Lake describes the situation as it meets the world; the inner (lower) trigram Heaven describes its inner disposition. Together they set the theme of Break-through.
The Six Lines
初九 · Line 1 Power in the forward stride: advancing unequal to the task means blame.壮于前趾，往不胜为咎。
九二 · Line 2 Alarm cries at dusk, armed trouble by night — with vigilance, no fear.惕号，莫夜有戎，勿恤。
九三 · Line 3 Power showing in the face bodes ill. The noble one, fully resolved, walks alone through rain, soaked and resented — no blame.壮于頄，有凶。君子夬夬独行，遇雨若濡，有愠无咎。
九四 · Line 4 Flayed and faltering: led like a sheep, remorse would vanish — but the words go unheeded.臀无肤，其行次且；牵羊悔亡，闻言不信。
九五 · Line 5 Uprooting the stubborn weed with utmost resolve: walking the middle, no blame.苋陆夬夬，中行无咎。
上六 · Line 6 No cry of warning left — in the end, misfortune.无号，终有凶。
Reading Hexagram 43 for Your Question
When Break-through appears without changing lines, the judgment above stands as the whole answer. When you cast changing lines (a 6 or a 9), read those line texts first — they are the most specific guidance — then look to the relating hexagram they form for where the situation is heading. For love, career, or a decision, apply the theme of Break-through to your own circumstances rather than reading it as a fixed prediction.
Ask the oracle your own question and see whether Break-through answers.
