There were once two brothers who had equal right to the throne. One brother schemed constantly to discredit his brother while the other took it all in stride. One day the scheming brother erred while plotting his way to the throne and had an accident, and died.
Out of body now, he watched as the other brother took seat upon the coveted throne. But he saw something there that stopped him in mid thought. His brother, although sitting upon the throne, had deep within him memories of his dead brother, and a love for him and an admiration, which assisted him in every decision he made.
So while the one schemed and plotted and did everything to make his brother look unworthy, and died, the other always loved him, regardless, and lived, and ruled with the other in his heart and mind, thus sharing this seat.
