The judgment

The Judgment

The Corners of the Mouth. Perseverance brings good fortune. Pay heed to the providing of nourishment and to what a person seeks to fill their own mouth with.
The image

The Image

At the foot of the mountain, thunder: the image of Providing Nourishment. Thus the superior person is careful of their words and temperate in eating and drinking.

Master Wei Lin's Interpretation

Interpretation by Master Wei Lin, Chinese Metaphysics Scholar, pattern recognition, not fortune-telling

The open mouth, what you take in and what you put out. Nourishment asks you to examine what you're feeding: your body, your mind, your spirit, your relationships. What are you consuming? What words are you speaking? Your question is being reflected through this lens: the quality of what you take in determines the quality of what you can give out.

The moving lines

The Six Lines

When a changing line appears in your reading, its text carries special guidance for your situation.

Line 1 (bottom)

You let your magic tortoise go, and look at me with the corners of your mouth drooping. Misfortune.

Line 2

Turning to the summit for nourishment, deviating from the path to seek nourishment from the hill. Continuing to do this brings misfortune.

Line 3

Turning away from nourishment. Perseverance brings misfortune. Do not act thus for ten years. Nothing serves to further.

Line 4

Turning to the summit for provision of nourishment brings good fortune. Spying about with sharp eyes like a tiger with insatiable craving. No blame.

Line 5

Turning away from the path. To remain persevering brings good fortune. One should not cross the great water.

Line 6 (top)

The source of nourishment. Awareness of danger brings good fortune. It furthers one to cross the great water.
