Brāhmaṇa-vandana: Criteria for Veneration, Disciplined Speech, and Protective Kingship (अनुशासनपर्व, अध्याय ८)
नारी तु पत्यभावे वै देवरं कुरुते पतिम् । पृथिवी ब्राह्मणालाभे क्षत्रियं कुरुते पतिम्
nārī tu patyabhāve vai devaraṃ kurute patim | pṛthivī brāhmaṇālābhe kṣatriyaṃ kurute patim |
Bhīṣma said: “When a woman is without her husband, she may accept the husband’s younger brother as her spouse; in the same way, when the Earth does not obtain a Brāhmaṇa, she accepts a Kṣatriya as her lord. The point is that rightful authority is graded: the higher, dharma-guiding order is preferred, but in its absence a secondary protector-ruler is accepted for the sake of social stability.”
भीष्म उवाच
Bhīṣma teaches a hierarchy of rightful leadership: ideally the Brāhmaṇa (as dharma-guiding authority) is foremost, but when that is unavailable, the Kṣatriya is accepted as ruler-protector to preserve order; the analogy illustrates pragmatic dharma—choosing the next-best legitimate support in a crisis.
In Bhīṣma’s instruction on dharma and governance, he uses a social analogy (a widow accepting the devara) to explain how the Earth/kingdom accepts a Kṣatriya’s sovereignty when a Brāhmaṇa is not present to lead—emphasizing continuity of protection and rule.
