दोषैरेतैः कुलघ्नानां वर्णसंकरकारकैः। उत्साद्यन्ते जातिधर्माः कुलधर्माश्च शाश्वताः॥

doṣair etaiḥ kula-ghnānāṃ varṇa-saṃkara-kārakaiḥ / utsādyante jāti-dharmāḥ kula-dharmāś ca śāśvatāḥ

Every pillar of social order that took generations to build — destroyed in one war.

Word by word (4)
doṣair etaiḥ kula-ghnānām
— by these faults of those who destroy the family
varṇa-saṅkara-kārakaiḥ
— causing the intermixing of castes · 'Varṇa-saṅkara' — literally mixing of colors/castes. In Arjuna's argument, social order depends on clearly defined roles; war destroys those roles and the traditions that sustain them.
utsādyante jāti-dharmāḥ
— the caste laws are destroyed
kula-dharmāś ca śāśvatāḥ
— and the eternal family traditions collapse · Arjuna's argument is sociological and traditional, not metaphysical. He will need a deeper teaching — which begins in V2.11.

'By the evils caused by those who destroy families and create social disorder, the eternal duties of both caste and family are wiped out.'

A modern analogy

Every functioning society depends on accumulated social infrastructure: laws, customs, trust, roles, responsibilities. It takes generations to build. A single war, a single upheaval, can destroy in days what took centuries to construct. Arjuna is naming this cost precisely.

Take with you

  • The cumulative argument (V39-42) shows that Arjuna understands second and third-order consequences — a mark of genuine ethical reasoning.
  • Social institutions are fragile in a way that individual human capability is not — they depend on continuous maintenance.
  • This verse concludes Arjuna's most structured argument. What follows (V43-46) returns to personal moral declaration.

Verse 42 concludes the social-consequence argument. Arjuna has constructed an elegant causal chain: Family destroyed → family dharma lost → adharma enters → women corrupted → social order mixed → ancestors fall → eternal duties of caste and family destroyed. This is Arjuna's most intellectually complete performance in Chapter 1. He is thinking structurally, consequentially, and across time. His error is not in the argument itself — the consequences he predicts are genuinely bad — but in the conclusion: that inaction is therefore preferable. The Gita will respond that the same clarity about consequences, grounded in dharma rather than personal relationship, produces a different answer.
