Hexagram 27: Nourishment (頤) & Tzolkin
Hexagram 27 Nourishment (頤 Yí) in I Ching and Tzolkin: Mountain over Thunder, the mouth's corners. Maps to kins 105–108, the Red Serpent wavespell and the body's wisdom.
頤 yí · Nourishment
Nourishment (頤, Yí) is the hexagram of the Corners of the Mouth — a still Mountain resting above Thunder moving at its foot. Its shape, one yang line at top and bottom enclosing four yin lines between, resembles an open jaw. The image counsels restraint in speech and moderation in eating and drinking — feeding body, mind, and spirit with attention.
In the Argüelles Codon system, hexagram 27 corresponds to kins 105–108 of the Tzolkin — the first four tones opening the Red Serpent wavespell. Kin 105 carries the seal of the Serpent (Life Force), the body’s instinctive wisdom, the very dimension the hexagram addresses. The wavespell’s next kins — Worldbridger (Death), Hand (Accomplishment), Star (Elegance) — move through the full color cycle, red, white, blue, yellow, as the Corners of the Mouth trace the path from first bite to full sustenance.
Read side by side, both traditions point to a shared principle: a new cycle, whether a wavespell or an ordinary day, begins with what we let in — food, word, attention. This is an interpretive bridge, not a proven numerical dependency.
The Judgment
The Corners of the Mouth. Perseverance brings good fortune. Pay heed to the providing of nourishment — for body, mind, and spirit. Be mindful of what you consume and share.
The Image
At the foot of the mountain, thunder. The superior person is careful of their words and temperate in eating and drinking.
