Hexagram 27 頤 Yí for Health Questions 頤 問健康

Hexagram 27 (頤, Yí) is one of the 64 classical I Ching hexagrams. Wilhelm’s English translation renders the hexagram’s name as “The Corners of the Mouth (Providing Nourishment)”. This page describes how classical commentary reads this hexagram when received in answer to a health question.

“The Corners of the Mouth. Perseverance brings good fortune. Pay heed to the providing of nourishment and to what a person seeks to fill their own mouth with.”
— classical judgment text

“At the foot of the mountain, thunder: the image of providing Nourishment. Thus the noble person is careful of their words and temperate in eating and drinking.”
— classical image text

The hexagram’s general theme

What you put into the jaws — words, food, ideas — becomes what you are. Discipline of intake is the discipline of character.

Classical keywords: nourishment, intake, speech and food, what you consume, self-discipline.

頤 Yí read for health questions

Classical I Ching commentary reads health questions through the hexagram’s register of vitality, balance, and the body’s relationship with its environment. The hexagram describes the field of forces around the health question; classical doctrine reads whether the moment favours active intervention, restorative rest, professional consultation, or acceptance and adaptation. Note: the I Ching reading is interpretive, not medical — serious health concerns require qualified medical advice.

For health-domain questions specifically, the hexagram’s register touches: physical health and consumption. These are among the modern interpretive resonances classical commentary recognises in the hexagram.

Classical guidance for the hexagram: Examine carefully what you take in and what you give out. Don't envy others' nourishment. Source your own.

Why a generic hexagram-for-health interpretation falls short

This page describes what classical commentary reads when Hexagram 27 is received for a health question — the hexagram’s general register applied to the health domain. But a complete I Ching reading for a specific question requires the casting method (yarrow vs three-coin), identification of changing lines, the resulting secondary hexagram, and integration with the querent’s specific BaZi chart. Without those, the reading is reference-level — the broad register, not the chart-specific application. For chart-aware reading on a specific health question, book a BaZi consultation. The four-pillar chart identifies the elemental balance the body needs, layered with the I Ching reading for timing-aware health diagnostics. Note: this is interpretive reading, not medical advice.

Hexagram 27 頤 Yí read for a health question is one input in a complete classical reading — not the whole answer. Classical I Ching practice layers four inputs together; the hexagram is only the second.

1. The casting method and quality of the question. Yarrow stalk vs three-coin vs other methods produce different statistical distributions of changing lines. The framing of the question itself shapes the answer — vague or compound questions return readings that classical commentary specifically warns against. A consultation handles both the casting and the question-framing as part of the reading.
2. The hexagram itself. What this page describes — the classical register of the hexagram and how it reads for the specific question type. Useful as reference; not sufficient on its own.
3. Changing lines and the secondary hexagram. Most I Ching readings produce one or more changing lines (动爻) which determine a secondary hexagram (之卦) representing how the situation evolves. The reading is the primary hexagram’s present register modulated by the changing lines and resolved by the secondary hexagram’s future register. Identifying which lines have changed and reading the secondary hexagram is the chart-casting skill that consultation provides.
4. The querent’s specific BaZi chart. Classical practice layers the I Ching reading with the querent’s four-pillar BaZi chart — the chart describes the querent’s position within the field of forces the hexagram describes. Two people receiving the same hexagram in answer to the same kind of question often need different responses based on their charts.

This page describes the second input — Hexagram 27 頤’s register for health questions. The reading is a useful starting reference. It is not a substitute for a chart-aware reading that layers in the other three. Master Sean Chan’s BaZi consultation reads all four layers against your specific question.

• Recognise the hexagram’s general register first. What you put into the jaws — words, food, ideas — becomes what you are. Discipline of intake is the discipline of character.
• Read it through the health-question lens. Classical I Ching commentary reads health questions through the hexagram’s register of vitality, balance, and the body’s relationship with its environment. The hexagram describes the field of forces around the health question; classical doctrine reads whether the moment favours active intervention, restorative rest, professional consultation, or acceptance and adaptation. Note: the I Ching reading is interpretive, not medical — serious health concerns require qualified medical advice.
• Note the classical guidance. Examine carefully what you take in and what you give out. Don't envy others' nourishment. Source your own.
• Recognise that this is one input of four. A complete I Ching reading layers the casting method, the hexagram, the changing lines and secondary hexagram, and the querent’s BaZi chart together. Book a chart-aware consultation to combine all four layers.
