Hexagram Mirrors - Line Reflections
(line pathways)

(39.2 and 48.2 complement each other: in both it is not your fault, but in 39.2 you have to adapt, in 48.2 you have to find a way)
(40.5 and 47.5 complement each other: in 40.5 there are little openings, in 47.5 you make use of them)
(all yang lines of Mirror 39.2 are yin lines in Mirror 21.2 and vv)
Mirror 39.2 is about using your potential when things are limited
Mirror 21.2 is about the integrity of what you do, having limits
