One who was born in the house of a warrior, regardless of his rank or class, first acquaints himself with a man of military feats and achievements in loyalty....Everyone knows that if a man doesn't hold filial piety toward his own parents he would also neglect his duties toward his lord. Such a neglect means a disloyalty toward humanity. Therefore such a man doesn't deserve to be called 'samurai'.
