अकृत्वा शत्रुसंहारमगत्वाखिलभूश्रियम् ।राजाहमिति शब्दान्नो राजा भवितुमर्हति ॥ ६६ ॥
In plain words
Without defeating his enemies, without actually taking hold of the whole realm's wealth, a man doesn't become a king just by declaring, 'I am the king.'
Close to the Sanskrit
Without having destroyed [his] enemies, without having attained the entire glory of the kingdom, merely from the utterance 'I am king,' [a man] does not deserve to be [called] king.
