Great Possession (火天大有)

Great gains: a sign of abundant harvest — stay humble to hold what you have.
Original Chinese judgment (通行本《周易》): 「元亨。」
The English above is 1518's plain summary of the hexagram's theme, not a canonical translation. For a canonical public-domain English translation, see James Legge, The Yî King (1899). Line texts (yao ci) are not reproduced here.
Structure
Great Possession is built from two trigrams: the upper is 离 (☲, Fire) and the lower is 乾 (☰, Heaven). Reading the hexagram starts from the image of the two trigrams together, then settles onto the theme above.
How this hexagram is used
In divination, the primary hexagram (Great Possession) frames the present situation. If your cast produces a moving line, it marks where change is happening, and the changed hexagram shows where things are heading. Cast a hexagram to see whether you draw this one.

The Chinese judgment is the source text; the hexagram structure and casting are deterministic implementations of public traditional rules. Interpretation is a traditional cultural reference, not professional advice. See all 64 in the hexagram index, and the Chinese page at 火天大有.
