The Secret of the Golden Flower (Chinese: 太乙金華宗旨; pinyin: Tàiyǐ Jīnhuá Zōngzhǐ) is a Chinese Taoist classic about neidan (inner alchemy) meditation.
The text of The Secret of the Golden Flower is attributed to Lü Dongbin of the late Tang dynasty. It is now known to have originated hundreds of years later, and was first published in the early Qing dynasty (清代前期), circa 1668–1692.
