tasmat sarvatmana rajan
gas ca hanmo havir-dughah
tasmat—therefore; sarva-atmana—in every respect; rajan—O King; brahmanan—the brahmanas; brahma-vadinah—who maintain the brahminical culture, centered around Visnu; tapasvinah—persons who are engaged in austerities; yajna-silan—persons engaged in offering sacrifices; gah ca—cows and persons engaged in protecting cows; hanmah—we shall kill; havih-dughah—because they supply milk, from which clarified butter is obtained for the offering of sacrifice.
O King, we, who are your adherents in all respects, shall therefore kill the Vedic brahmanas, the persons engaged in offering sacrifices and austerities, and the cows that supply milk, from which clarified butter is obtained for the ingredients of sacrifice.
