Mountain as a lower or upper trigram
As the lower trigram, Mountain describes the inner or initiating three lines of a hexagram. As the upper trigram, it forms the outer or completing three lines. The meaning of a full hexagram comes from the complete six-line figure and textual tradition, not from simply adding two trigram keywords together.
