21
Hexagram 21, Biting Through, is about decisive correction, confronting obstruction, and restoring clarity through firm but just action.
Line meaning
Breaking an entrenched pattern takes discipline. Do not drift back into old habits while doing the hard work.
Parent judgement
Biting Through has success. It is favorable to let justice be administered. This points to the need for clear standards, fair consequences, and action that removes obstruction without becoming cruel or reactive.
Life application
In daily life, Hexagram 21 favors hard conversations, clean decisions, and direct correction where confusion or injustice has built up. It helps when avoidance has made the problem worse and when truth needs to be expressed with firmness and restraint.
Changing line context
This line is read within Hexagram 21, Biting Through. When a single changing line is active, it points to the most immediate pressure, correction, or opening inside the larger hexagram pattern.
Use the parent hexagram for the wider situation, then let Line 4 show where the change is concentrating right now.
