Readiness for exertion in kings is the root of kingly duties. This has been said by Vrihaspati. Listen to the verses sung by him: 'By exertion the amrita was obtained; by exertion the Asuras were slain, by exertion Indra himself obtained sovereignty in heaven and on earth. The hero of exertion is superior to the heroes of speech. The heroes of speech gratify and worship the heroes of exertion.[169]' The king that is destitute of exertion, even if possessed of intelligence, is always overcome by foes like a snake that is bereft of poison.
