Like the tortoise protecting its limbs by withdrawing them within its shell, ministers should protect their own counsels. They should, even thus, conceal their own laches. Those ministers of a kingdom that succeed in concealing their counsels are said to be possessed of wisdom. Counsels constitute the armour of a king, and the limbs of his subjects and officers. A kingdom is said to have its roots in spies and secret agents, and its strength is said to lie in counsels of policy. If masters and ministers follow each other for deriving support from each other, subduing pride and wrath, and vanity and envy, they may then both become happy. A king should also consult with such ministers as are free from the five kinds of deceit. Ascertaining well, in the first instance, the different opinions of the three amongst them whom he has consulted, the king should, for subsequent deliberation, repair to his preceptor for informing him of those opinions and his own. His preceptor should be a Brahmana well versed in all matters of virtue, profit, and pleasure. Repairing, for such subsequent deliberation, to him, the king should, with collected mind, ask his opinion. When a decision is arrived at after deliberation with him, the king should then, without attachment, carry it out into practice. They that are conversant with the conclusions of the science of consultation say that kings should always hold consultation in this way. Having settled counsels in this way, they should then be reduced to practice, for then they will be able to win over all the subjects. There should be no dwarfs, no humpbacked persons, no one of an emaciated constitution, no one who is lame or blind, no one who is an idiot, no woman, and no eunuch, at the spot where the king holds his consultations. Nothing should move there before or behind, above or below, or in transverse directions.
