अधर्माभिभवात्कृष्ण प्रदुष्यन्ति कुलस्त्रियः। स्त्रीषु दुष्टासु वार्ष्णेय जायते वर्णसङ्करः
adharmābhibhavāt kṛiṣhṇa praduṣhyanti kula-striyaḥ strīṣhu duṣhṭāsu vārṣhṇeya jāyate varṇa-saṅkaraḥ
When irreligion spreads, the women of the house start to stray; when they lose their purity, adulteration of the lineage follows.
Translated by Shri Purohit Swami
O Krishna, by the prevalence of impiety, the women of the family become corrupt; and, when women are corrupted, O Varshenya (descendant of Vrishni), intermingling of castes arises.
Translated by Swami Sivananda
