Prakasha had a son named Vagindra who was the foremost of all silent reciters of sacred Mantras. Vagindra begot a son named Pramati who was a perfect master of all the Vedas and their auxiliaries. Pramati begot upon the Apsara Ghritachi a son who was named Ruru.
तस्यात्मजश्च प्रमितिर्वेदवेदाङ्गपारगः। घृताच्यां तस्य पुत्रस्तु रुरुर्नामोदपद्यत॥
