Trigram
A Trigram is a structure of three Lines. Each Hexagram is composed of two trigrams:
- The Lower Trigram: Lines 1, 2, and 3.
- The Upper Trigram: Lines 4, 5, and 6.
The relationship between the lower and upper trigrams (e.g., Harmony, Resonance) is fundamental to understanding the deeper mechanics of Profile and the internal structure of the Gates.
