Dāyavibhāga (Inheritance Apportionment) and Household Precedence — Dialogue of Yudhiṣṭhira and Bhīṣma
बन्धुभि: समनुज्ञाते मन्त्रहोमौ प्रयोजयेत् । तथा सिद्धयन्ति ते मन्त्रा नादत्ताया: कथंचन
bandhubhiḥ samanujñāte mantrahomau prayojayet | tathā siddhyanti te mantrā nādattāyāḥ kathaṃcana ||
Bhishma dijo: «Cuando los parientes de la muchacha han dado su consentimiento, deben emplearse los mantras nupciales y la ofrenda al fuego (homa). Solo entonces esos mantras se vuelven eficaces y cumplen su propósito. Para una joven que no ha sido debidamente entregada en matrimonio por sus tutores, la aplicación ritual de los mantras no prospera de ningún modo: tal unión no se considera un matrimonio correctamente consagrado por el rito védico.»
भीष्म उवाच
Ritual validity depends on rightful authorization: marriage mantras and homa are considered efficacious only when performed with the consent of the girl’s guardians/kinsmen and when she is duly ‘given’ in marriage; otherwise the rite is treated as not properly accomplished.
In Bhishma’s dharma-instruction discourse (Anushasana Parva), he lays down a rule about the proper performance of marriage rites, emphasizing consent and formal guardianship-based giving as prerequisites for the success of the Vedic mantras and homa.
