Let him draw them for Indra Marutvat (accompanied by the Maruts), and not for the Maruts likewise. For were he also to draw cups for the Maruts, he would make the people refractory to the nobility. He thus assigns to the Maruts a share therein after Indra, whereby he makes the people subservient and obedient to the nobility: therefore let him draw the cups for Indra Marutvat, and not for the Maruts likewise.
