Pṛthivī-dohaṇa (The Milking of the Earth) and the Praise of King Pṛthu
चातुर्वर्णमयसमाकीर्णा रक्षिता तेन धीमता / एवंप्रभावोराजासीद्वैन्यः सद्विजसत्तमाः
cāturvarṇamayasamākīrṇā rakṣitā tena dhīmatā / evaṃprabhāvorājāsīdvainyaḥ sadvijasattamāḥ
She (the Earth) was filled with the four varṇas and was protected by that wise one (Pṛthu); O best of the twice-born, such indeed was the might and splendor of King Vainya.
