Varāha-uddhāraṇa and the Re-constitution of Bhū-maṇḍala
Earth after Pralaya
निस्तेजसो ऽल्पवीर्याश्च शूद्रांस्तानब्रवीच्च सः / तेषां कर्माणि धर्मांश्च ब्रह्मा तु व्यदधात्प्रभुः
nistejaso 'lpavīryāśca śūdrāṃstānabravīcca saḥ / teṣāṃ karmāṇi dharmāṃśca brahmā tu vyadadhātprabhuḥ
Those devoid of splendor and of little strength he called Śūdras; and their duties and their dharma were ordained by Brahmā, the Lord.
