The Secret of the Golden Flower (Chinese: 太乙金華宗旨; pinyin: Tàiyǐ Jīnhuá Zōngzhǐ) is a Chinese Taoist book on neidan (inner alchemy) meditation, which also mixes Buddhist teachings with some Confucian thoughts.[1] It was written by means of the spirit-writing (fuji) technique, through two groups, in 1688 and 1692.[2] After publication of the translation by Richard Wilhelm, with commentary by Carl Gustav Jung, it became modernly popularized among Westerners as a Chinese "religious classic", and is read in psychological circles for analytical and transpersonal psychology considerations of Taoist meditations,[3][4] although it received little attention in the East.[1]
