The first replied: 'How is it with this Raikva with the car of whom thou speakest?' The other answered: 'As (in a game of dice) all the lower casts belong to him who has conquered with the Krita cast, so whatever good deeds other people perform, belong to that Raikva. He who knows what he knows, he is thus spoken of by me.

In plain words: The first bird asked who this Raikva was. The second bird explained that just as the winning throw in a dice game takes all the lower throws, all the good that other people do is included in Raikva. That is because Raikva knows the highest truth.
