Pṛthivyāyāma-vistara (Extent and Divisions of the Earth) / पृथिव्यायामविस्तरः
ब्राह्मणाः क्षत्रिया वैश्या मध्ये शूद्राश्च भागशः / इज्यायुधवणिज्याभिर्वर्त्तयन्तो व्यवस्थिताः
brāhmaṇāḥ kṣatriyā vaiśyā madhye śūdrāśca bhāgaśaḥ / ijyāyudhavaṇijyābhirvarttayanto vyavasthitāḥ
In the middle dwell brāhmaṇas, kṣatriyas, vaiśyas, and śūdras, each in their allotted portions. They live established in their duties—worship and sacrifice, the bearing of arms, and trade.
