I Ching Oracle Lookup - Hexagram 27: Nourishment

Yin-Yang symbol

Welcome to Hexagram 27, Nourishment. The table below maps every combination of changing lines to its resulting hexagram — 63 transformations plus the unchanging reading. The notation reads from the bottom line upward: 27.1.5 means Hexagram 27 with lines 1 and 5 changing.

About the Transformations of Hexagram 27

Hexagram 27, Nourishment (頤 Yí), places Thunder below Mountain. Its yang lines occupy the first and sixth positions, enclosing four yin lines and giving the whole figure vertical symmetry. Changes in the lower trigram reconfigure Thunder and the opening stage of the pattern; changes in the upper trigram reshape Mountain and its culmination. Movement across both halves alters the relation between activation at the base and containment at the top.

Every line marked as changing in the table inverts, and the recomposed pattern then resolves into a second hexagram. The mapping contains six transformations produced by single moving lines and fifty-seven produced by multi-line combinations. It also includes the unchanging reading, for which no line reverses, no secondary figure appears, and the Judgment of Hexagram 27 alone governs.

With all six positions inverted, Nourishment becomes Hexagram 28, Great Excess, its exact complement. Great Excess is also its King Wen partner. Because Hexagram 27 is vertically symmetric and reads identically upside down, inversion returns the original figure rather than producing its neighbor; the pair is therefore established by complementation. This symmetry and complementary pairing mechanism are exceptional properties shared with seven other figures.
