ब्राह्मण्यं समनुप्राप्तं विश्वामित्रादिभिर्नृपैः / येनयेनाभिधानेन ब्राह्मण्यं क्षत्रिया गताः
brāhmaṇyaṃ samanuprāptaṃ viśvāmitrādibhirnṛpaiḥ / yenayenābhidhānena brāhmaṇyaṃ kṣatriyā gatāḥ
Kings such as Viśvāmitra fully attained brāhmaṇya. By what titles and by what means did kṣatriyas come to that brahminhood?
