Those who turn the reins of their desires from unlawful things have surpassed Rustam[31] and Sām[32] in valour.
None is so fearful of the enemy as thou, slave of thine own passions.
Thy earthly body is a city, containing both good and evil; thou art the King, and Reason is thy wise minister.
In this city, the headstrong men pursue their trades of avarice and greed; Resignation and Temperance are the citizens of fame and virtue; Lust and Wantonness the thieves and pick-pockets.
When the king shows favour to the wicked, how can the wise remain in peace?
The passions of evil, envy, and hatred are inherent in thee as is the blood of thy veins. If these thine enemies gained in strength they would turn their heads from thy rule and counsel; no resistance do they offer when they see the mailed fist of Reason.
Night-thieves and vagabonds wander not in the places where the patrols guard.
The chief who punishes not his enemy is bereft of power by the strength of the latter.
More on this point I will not speak—a word suffices to him who puts into practice what he reads.
