Mbh 12.120.2d

That king is said to be conversant with the duties of king-craft who rewards his officers and subjects publicly (for any good they do), who chastises those that deserve chastisement, who protects his own self, and who protects his kingdom from every evil. Like the Sun shedding his rays upon everything below, the king should always look after his kingdom himself, and aided by his intelligence he should supervise all his spies and officers. The king should take wealth from his subjects at the proper time. He should never proclaim what he does. Like an intelligent man milking his cow every day, the king should milk his kingdom every day. As the bee collects honey from flowers gradually, the king should draw wealth gradually from his kingdom for storing it. Having kept apart a sufficient portion, that which remains should be spent upon acquisition of religious merit and the gratification of the desire for pleasure. That king who is acquainted with duties and who is possessed of intelligence should never waste what has been stored. The king should never disregard any wealth for its littleness; he should never disregard foes for their powerlessness; he should, by exercising his own intelligence, examine his own self; he should never repose confidence upon persons destitute of intelligence. Steadiness, cleverness, self-restraint, intelligence, health, patience, bravery, and attention to the requirements of time and place,--these eight qualities lead to the increase of wealth, be it small or be it much. A little fire, fed with clarified butter, may blaze forth into a conflagration. A single seed may produce a thousand trees. A king, therefore, even when he hears that his income and expenditure are great, should not disregard the smaller items. A foe, whether he happens to be a child, a young man, or an aged one, succeeds in slaying a person who is heedless. An insignificant foe, when he becomes powerful, may exterminate a king.
