12.2.7

एवं प्रजाभिर्दुष्टाभिराकीर्णे क्षितिमण्डले । ब्रह्मविट्‍क्षत्रशूद्राणां यो बली भविता नृप: ॥ ७ ॥

evaṁ prajābhir duṣṭābhir ākīrṇe kṣiti-maṇḍale brahma-viṭ-kṣatra-śūdrāṇāṁ yo balī bhavitā nṛpaḥ

evam
in this way
prajābhiḥ
with populace
duṣṭābhiḥ
corrupted
ākīrṇe
being crowded
kṣiti-maṇḍale
the earth globe
brahma
among the brāhmaṇas
viṭ
vaiśyas
kṣatra
kṣatriyas
śūdrāṇām
and śūdras
yaḥ
whoever
balī
the strongest
bhavitā
he will become
nṛpaḥ
the king

As the earth thus becomes crowded with a corrupt population, whoever among any of the social classes shows himself to be the strongest will gain political power.
