Zhouyi BenyiLine statement
'Sheng' (calamity/fault) is pronounced as a fanqie of sheng and ling.
Six occupies the top of the trigram of movement with a yin line, dwelling at the extreme of yin excess; its excess is already too high and far removed. Hence its image and omen are like this.
Some say: 'meeting excess' should probably also be understood as 'excess in meeting,' sharing the same meaning as Nine in the Fourth Place; it is unknown whether this is so.
