The Duta (ambassador) is the king's eyes, ears, and voice abroad. Kautilya identifies three types: Nisrishtartha (plenipotentiary with full powers), Parimitartha (with limited mandate), and Sasanaharah (mere message bearer). This chapter explores ambassador selection, diplomatic immunity, reading intentions behind words, the art of negotiation, when to reveal truth and when to remain silent. A skilled duta can achieve more than an army.
