 the kings companion should be of moderate nature of moderate humours sound in limbs and morals. he should not be disturbed by yellow bile and move about excessively nor should dampness and phlegm overpower him and cause him to urinate spit yawn and sleep prolong. nor should black bile bore him cause him to think too long have too many wishes and spoil his temperament. as for the sanguine he is not included in these blameworthy categories since the body needs him as it needs its composition and soundness.
ينبغي أن يكون نديم الملك معتدل الطبيعة، معتدل الأخلاط، سليم الجوارح والأخلاق، لا الصفراء تقلقه وتكثر حركته، ولا الرطوبة والبلغم يقهره ويكثر بوله وبزقه وتثاؤبه ويطيل نومه، ولا السوداء تضجره وتطيل فكره وتكثر أمانيه وتفسد مزاجه. فأما الدموي فليس يدخل في هذه الأقسام المذمومة، إذ كان بالبدن إليه حاجة كحاجته إلى تركيبه وسلامته.
