It is for these reasons that they that are wise are ever careful of both virtue and wealth, for a union of virtue and wealth is the essential requisite of pleasure, as fuel is the essential requisite of fire. Pleasure hath always virtue for its root, and virtue also is united with pleasure. Know, O monarch, that both are dependent on each other like the ocean and the clouds, the ocean causing the clouds and the clouds filling the ocean. The joy that one feeleth in consequence of contact with objects of touch or of possession of wealth, is what is called pleasure. It existeth in the mind, having no corporeal existence that one can see. He that wisheth (to obtain) wealth, seeketh for a large share of virtue to crown his wish with success. He that wisheth for pleasure, seeketh wealth, (so that his wish may be realised). Pleasure however, yieldeth nothing in its turn. One pleasure cannot lead to another, being its own fruit, as ashes may be had from wood, but nothing from those ashes in their turn. And, O king, as a fowler killeth the birds we see, so doth sin slay the creatures of the world. He, therefore, who misled by pleasure or covetousness, beholdeth not the nature of virtue, deserveth to be slain by all, and becometh wretched both here and here-after. It is evident, O king, that thou knowest that pleasure may be derived from the possession of various objects of enjoyment. Thou also well knowest their ordinary states, as well as the great changes they undergo.
