97.19

郊特生曰。魂氣歸於天。形魄歸於地。故祭求諸陰陽之義。祭義曰。氣也者神之盛。魂也者鬼之盛。

The "Jiaotesheng" [chapter] says: "The hun-qi returns to heaven; the bodily po-soul returns to earth. Therefore, sacrificial offerings seek them in the principles of yin and yang." The "Jiyi" [chapter] says: "Qi is the abundance of the spirit (shen); hun is the abundance of the ghost (gui)."
