From the beginning it has been said that the duty of the Kshatriya is to protect all creatures. The king gets a fixed share of the merits acquired by his subjects. By that means the king becomes gifted with righteousness.
क्षत्रियस्य स्मृतो धर्मः प्रजापालनमादितः। निर्दिष्टफलभोक्ता हि राजा धर्मेण युज्यते॥
