From the predominance of impiety, oh Kṛṣṇa, the women of the family are corrupted; when women are corrupted, oh Vārṣṇeya, there arises the confusion of castes

The argument is now socio-biological. Arjuna presents a theory of social collapse: adharma → corruption of women → varṇa-saṅkaraḥ (confusion/mixture of castes). The concern for kula-strī (women of family) reflects the patriarchy of the time: women are guardians of the family line, and their “corruption” (duṣṭāsu from praduṣyanti) implies loss of genealogical purity.

Vārṣṇeya (descendant of Vṛṣṇi, Kṛṣṇa’s dynasty) is an implicit reminder: the Yadu dynasty also faced varṇa crisis. The saṅkara (mixture, confusion) is the supreme fear of a hierarchical society: the impossibility of distinguishing roles, structural chaos.

There is historical irony: Arjuna himself, as son of Indra but raised as kṣatriya, represents certain varṇa complexity.
