The Arthshastra is a treatise on statecraft, economic policy and military strategy. It discusses the acquisition and protection of the means of livelihood as well as ensuring the welfare of citizens. The two main aims of the Arthshastra are administration and protection of the state (Palana) and conquest and acquisition of territory (Labha). It provides guidance on practical aspects of internal and external administration. The Arthshastra advocates for a monarchy and describes the qualities and duties required of a ruler to protect subjects and ensure their well-being and prosperity. It also outlines administrative principles for revenue collection, personnel management and public administration that still have relevance today.
