Quote from : Leadership Secrets From The Mahabharata Book

Readiness for action is the root of all kingly duties. Listen to the verse sung by Vrihaspati: By exertion the amrita was obtained, by exertion the asuras were slain and by exertion Indra obtained sovereignity in heaven and on earth. The heroes of exertion are superior to the heroes of speech. The heroes of speech gratify the heroes of exertion.
