39 · Obstruction (JIǍN)
Obstruction begins where water blocks a mountain path. Seeing danger and stopping is an act of intelligence. The lines ask when to wait, return, serve through hardship, hold a connection, accept arriving friends, and seek worthy guidance.

The judgment
Obstruction: favourable to the southwest, unfavourable to the northeast; favourable to meet a great person. Steadfastness is auspicious.
The directions work as a classical contrast between a more open way and further mountain difficulty; they are not a travel instruction for every modern journey. Choose the workable path, seek capable counsel, and keep the right course.
