11.21.8

अकृष्णसारो देशानामब्रह्मण्योऽशुचिर्भवेत् । कृष्णसारोऽप्यसौवीरकीकटासंस्कृतेरिणम् ॥ ८ ॥

akṛṣṇa-sāro deśānām abrahmaṇyo ’sucir bhavet kṛṣṇa-sāro ’py asauvīra- kīkaṭāsaṁskṛteriṇam

akṛṣṇa-sāraḥ
without spotted antelopes
deśānām
among places
abrahmaṇyaḥ
where there is no devotion to the brāhmaṇas
aśuciḥ
contaminated
bhavet
is
kṛṣṇa-sāraḥ
possessing spotted antelopes
api
even
asauvīra
without saintly cultured men
kīkaṭa
(a place of low-class men, such as) the state of Gayā
asaṁskṛta
where people do not practice cleanliness or purificatory ceremonies
īraṇam
where the land is barren

Among places, those bereft of the spotted antelope, those devoid of devotion to the brāhmaṇas, those possessing spotted antelopes but bereft of respectable men, provinces like Kīkaṭa and places where cleanliness and purificatory rites are neglected, where meat-eaters are prominent or where the earth is barren, are all considered to be contaminated lands.
