Duration
Judgment
— I Ching · classical
亨，无咎，利贞，利有攸往。
Lasting constancy brings success and leaves nothing to fault; staying the course is rewarding, and it favors moving ahead.
Image
— Great Image
雷风，恒，君子以立不易方。
Thunder and wind reinforcing each other: this is Duration. Watching this, a person of principle plants their feet and doesn't waver from their chosen direction.
Six Lines
— Bottom to top
Modern Readings
— Interdisciplinary
Career & Management
Compliant operations, long-term strategic inertia, the daily grind of SOP. Avoid the 'three matches of a new official' followed by a quick fade. Execution needs the same patience tomorrow as today.
Psychology & Cognition
Overcome the three-minute enthusiasm. Build habit loops; understand that all major achievements are compound returns; keep the inner core steady amid changes outside.
Decision Guidance
Stand firm, do not change direction (li bu yi fang). Avoid the impulsive (line 3) and the agitated (line 6).
Integrated Reading
— Structure · timing · relations
Duration places The Arousing / Thunder above The Gentle / Wind, Wood. Read the lower trigram as the emerging ground and the upper trigram as the field, pressure, or constraint it must answer. The core theme is Duration · Constancy · Direction over restlessness. Relations: the opposite hexagram shows the shadow/complement (Increase); the inverse shows the other-side view (Influence); the nuclear hexagram shows the hidden internal mechanism (Breakthrough).
Line Path
Line path: Initial Six → Nine in the second → Nine in the third → Nine in the fourth → Six in the fifth → Six at the top. Read from bottom to top to see how the situation emerges, develops, crosses thresholds, and resolves.
Reflection Prompt
Am I acting from the proper position of Duration, or am I being pulled by turning duration into rigidity? What is the smallest reversible next move that respects the timing?
