वत्सेनेव हि धेनुं पितरमस्य सामन्तो दुह्यात् ॥ कZ_०१.१७.१६ ॥
vatseneva hi dhenuṃ pitaram asya sāmanto duhyāt
Just as a calf milks a cow, so would a frontier feudatory (sāmanta) ‘milk’ (exploit) this prince’s father (the king) through him.
A prince can become an instrument for feudatories to extract concessions from the king; therefore, the prince’s placement and influences must be controlled.
