2.1.5

apitā tu yathā bālas tathāsāṃvatsaro nṛpaḥ | amātṛko yathā bālas tathātharvavivarjitaḥ || arimadhye yathaikākī tathā vaidyavivarjitaḥ ||

Just as a child is fatherless, so is a king without an astrologer; / just as a child is motherless, so is one destitute of an Atharvan; / just as one is alone in the midst of enemies, so is one destitute of a physician.
