Zhouyi BenyiLine statement
Pronounce 夤 (yín) as yǐn-zhēn.
The limit (xiàn) is the boundary between the upper and lower parts of the body, namely the waist and hips.夤 (yín) means the spine.
Stopping at the calves merely means not advancing; but Nine in the Third Place, being excessively firm and unyielding, lacks the center and occupies the place of the waist.
Stopping at the waist, one can neither bend nor extend, and upper and lower are severed and divided, as if cleaving the spinal muscles. Danger suffocates the heart; the unease is extreme.
Dwelling in a yin position with a yin line, stopping when it is time to stop, it forms the image of keeping still one's body, and the divination is without blame.
