This said, whose meaning does not have much to clarify, to me reminds me of the fable of the dog and the piece of meat from the Greek Aesop ( 6th century a. d. C. ) it was then rewritten by other writers as the Archpriest of Hita from the 14th century and that in summary it says this: A dog to cross a river with a piece of meat in his mouth saw his image in the water, believing it to be another dog with one greater piece, so it dropped his to catch the other and thus was left with nothing. Moral refers to the meaning of the saying above: greed breaks the sack.
