Very Proper Motive of Revenge

Ankokuji Eikei…had his hiding-place revealed by a Ronin, who bore him a grudge for turning his former master out of his fief…. How gratified [Tokugawa Ieyasu] was may be gathered from his presenting ten pieces of gold to the Ronin, who at first emphatically refused to take it, declaring that his motive was only the very proper one of revenge, and that he did not wish to profit otherwise. But Ieyasu would not take a refusal, and so he received this quite large sum, but distributed it among the people of his village in true recluse style.
