brāhmaṇaiśca vidhīyante kṣatriyāḥ kṣatriyairviśaḥ
vaiśyāñchūdrā anuvartante parasparamanugrahāt //

The Brâhmanas by their kind behaviour should enlighten the Kṣatriyas and the latter should educate the Vaiśyas and they should, in their turn, lovingly mould up the Śûdras in their duties. Their hearts were directed to Varṇâśrama Dharma. Their dharma was not fruitless and, therefore, all their actions were attended with success merely by their Saṅkalaps or intentions. The people in their ordinary course were longlived, healthy, handsome, sturdy, religious and modest. Brahmâ laid down the orders of varṇa and âśrama etc., with great accuracy. He the sons of Brahmâ framed the Saṁhitâs (or books) on medicine (how their health should be kept up), and practices of dharma and other mantras.—52-55.
