Hexagram 36: Darkening of the Light (明夷) & Tzolkin
Hexagram 36 Darkening of the Light (明夷 Míng Yí) in I Ching and Tzolkin: Earth over Fire, hidden brightness. It maps to kins 141–144 — strength maturing in concealment.
明夷 míng yí · Darkening of the Light
Darkening of the Light (明夷, Míng Yí) pairs Earth above Fire — brightness that has sunk beneath a heavy mass and must now shine without being seen. The hexagram describes a season of adversity: true wisdom lies not in openly resisting the dark, but in veiling one’s inner brightness and enduring patiently until the tide turns.
In the Argüelles Codon system, hexagram 36 corresponds to kins 141–144 of the Tzolkin calendar. Red Dragon (Birth), White Wind (Spirit), and Blue Night (Abundance) close out a thirteen-day wavespell at tones 11–13, carrying a motif of maturing in concealment before the energy is fully revealed. The fourth kin, Yellow Seed (Flowering) at tone 1, already opens a new wavespell — an impulse still buried, like a seed waiting underground for its own season to grow.
Set side by side, both traditions read this stretch of the cycle carefully — not as a proven correspondence, but as a lens: a force not yet ready to reveal itself, gathering strength in hiding for what will later flower.
The Judgment
Darkening of the Light. In adversity it furthers one to be persevering. Conceal your brightness in times of darkness — protect your inner light while navigating difficult circumstances.
The Image
The light has sunk into the earth. The superior person lives with the great mass and veils their brightness.
