8.1.52

sarvadravyaprayojakatvāt kośavyasanaṃ garīya iti //

The army may go to the enemy, or murder the king himself, and bring about all kinds of troubles. But finance is the chief means of observing virtuous acts and of enjoying desires. Owing to a change in place, time, and policy, either finance or the army may be a superior power; for the army is (sometimes) the means of securing the wealth acquired; but wealth is (always) the means of securing both the treasury and the army. Since all activities are dependent upon finance, financial troubles are more serious.
