Consider the following passage: A ruler of Vijayanagara composed an important work in Telugu dealing with the principles of statecraft. In this text, he emphasized the need for kings to improve harbours, encourage commerce, and ensure the import of valuable goods like horses, elephants, gems, pearls, and sandalwood. He advised rulers to treat foreign sailors with care if they arrived due to storms or illness, and to win over merchants of distant lands by offering them profits, presents, and a royal audience, so that these articles would not reach the enemies.
