inability of fire to generate earth

(fire is used to represent the kidney-YANG 〔the vital fire〕. Earth represents the spleen, when the YANG prin-ciple of the kidney is deficient and weak, the spleen and the stomach cannot recieve the warmth of this YANG prin-ciple. Such disease as backache, chillness of knees, etc. , will arise, cf. a maternal disease affecting its offspring. )
