He should further, enhance his stores of fuel, iron, chaff, charcoal, timber, horns, bones, bamboos, marrow, oils and ghee, fat, honey, medicines, flax, resinous exudations, rice, weapons, shafts, leather catgut (for bow-strings), caries, and strings and cords made of munja grass and other plants and creepers. He should also increase the number of tanks and well, containing large quantities of water, and should protect all juicy trees. He should entertain with honour and attention preceptors (of different sciences), Ritwijas, and priests, mighty bowmen, persons skilled in architecture, astronomers and astrologers, and physicians, as also all men possessed of wisdom and intelligence and self-restraint and cleverness and courage and learning and high birth and energy of mind, and capable of close application to all kinds of work. The king should honour the righteous and chastise the unrighteous. He should, acting with resolution, set the several orders to their respective duties. Ascertaining properly, by means of spies, the outward behaviour and the state of mind of the inhabitants of his city and provinces, he should adopt those measures that may be required. The king should himself supervise his spies and counsels, his treasury, and the agencies for inflicting chastisements. Upon these everything may be said to depend. With spies constituting his sight, the king should ascertain all the acts and intentions of his foes, friends, and neutrals.
