Hexagram Meaning

The Oracle Speaks

Thunder and lightning — energetic clarification. An obstacle between the teeth must be bitten through. Success through decisive legal or corrective action. Something blocks the connection between upper and lower; it must be removed by force. The obstruction in the pipeline demands surgical intervention.

The Six Lines — Changing Line Oracles

When a line is “changing” (old yin or old yang), its oracle activates. These texts reveal the specific mutation occurring at that position in the hexagram.

1

Line 1 (Yang — solid) — Bottom

His feet are fastened in stocks so that his toes disappear. No blame. First offense — minor constraint teaches the lesson.

2

Line 2 (Yin — broken)

Bites through tender meat so that his nose disappears. No blame. The fix goes deep but the problem is soft enough to resolve.

3

Line 3 (Yin — broken)

Bites on old dried meat and strikes on something poisonous. Slight humiliation. No blame. Legacy code contains hidden toxins.

4

Line 4 (Yang — solid)

Bites on dried gristly meat. Receives metal arrows. It furthers to be mindful of difficulties and persevere. Good fortune. The hardest bugs yield the best tools.

5

Line 5 (Yin — broken)

Bites on dried lean meat. Receives yellow gold. Perseveringly aware of danger. No blame. Gold extracted from the hardest work.

6

Line 6 (Yang — solid) — Top

His neck is fastened in the wooden cangue so that his ears disappear. Misfortune. The punishment is too severe — the system is over-restricted.
