Reflecting on this, they that are wise never grieve for want of universal dominion. O king, I again tell thee, adopt an equal conduct towards thy children, i.e., towards the sons of Pandu and thy own sons.

In plain words: Thinking about this, wise people do not grieve about not ruling the whole world. Vidura again urges King Dhritarashtra to treat his own sons and his nephews, the sons of Pandu, equally and fairly.
