《易经·井》卦中的“井”指墓穴,《井》卦原始说的是殷周时期宗教墓祭文化。从卦爻符号来看,内外卦(巽■、坎■)和互体卦(离■、兑■)都与古代祭祀有关;从卦辞和爻辞的内容来说,《井》卦描述的是墓葬祭祀的过程和祈求福佑的事情。 “Well” in “Yi Jing Wei” hexagrams refers to the grave, while “Well” Gua original refers to the religious tomb culture in the Yin and Zhou dynasties. From the hexagrams symbol, both inside and outside the hexagrams (巽 ■, ■ ■) and mutual hexagrams (from ■, against ■) are related to the ancient sacrificial; from the hexagrams and 爻 Ci’s content, the “well” Gua description is The process of burial and praying for blessings.
