A spring breaking ground at the mountain's foot: water that does not yet know its course. Méng is inexperience — not as a flaw, but as a stage that becomes dangerous only when it refuses to learn.
Its famous Judgment reverses the usual direction: it is not the teacher who seeks the student, but the student the teacher. Genuine questions receive answers; testing and pestering receive silence. The hexagram asks for sincerity about what you do not know.
問Méng suggests some part of this situation is being met with inexperience — perhaps a pattern you have not seen before, perhaps a partner's world you do not yet understand. The counsel is humble curiosity: ask real questions and accept the answers, rather than pretending to a certainty neither of you has earned.
Professionally, Méng is the apprentice's hexagram — and being the apprentice is honorable when done sincerely. Seek out someone who genuinely knows, ask once and listen fully. If you are the experienced one, its counsel flips: teach with patience, discipline without harshness, and do not answer those who only test.
The inner meaning of Méng is the beginner's mind consciously accepted. Somewhere you are new, and the suffering comes from disguising it. Thoroughness is the cure the Image prescribes: fill in each gap honestly, the way spring water fills each hollow in turn, and folly matures into clarity.
A line speaks only when it is a changing line in your own casting.
