摩訶止觀 8.71

8.71

又若多惛惛，是肝中無魂；多忘失前後，是心中無神；若多恐怖癲病，是肺中無魄；若多悲笑，是腎中無志；若多迴惑，是脾中無意；若多悵怏，是陰中無精。此名「六神病相」。

Furthermore, if one is frequently dazed and muddled, it is because there is no ethereal soul (hun) in the liver; if one frequently forgets what came before and after, there is no spirit (shen) in the heart; if one has frequent terror and madness, there is no corporeal soul (po) in the lungs; if one frequently weeps and laughs, there is no will (zhi) in the kidneys; if one frequently turns about in confusion, there is no intention (yi) in the spleen; if one is frequently melancholic and dissatisfied, there is no essence (jing) in the genitals. These are called the 'symptoms of illness of the six spirits.'
