Brāhmaṇa-vandana: Criteria for Veneration, Disciplined Speech, and Protective Kingship (अनुशासनपर्व, अध्याय ८)
भूय: स्यादुभयं दत्तं ब्राह्मणाद् यदकोपनात् । कुर्यादुभयत: शेषं दत्तशेषं न शेषयेत्
bhūyaḥ syād ubhayaṁ dattaṁ brāhmaṇād yad akopanāt | kuryād ubhayataḥ śeṣaṁ dattaśeṣaṁ na śeṣayet ||
Bhishma said: Again, what is given forth from a Brahmin who is free from anger becomes doubly effective. When spiritual power and fiery energy are applied from both sides, some residue may remain; but whatever force remains after being checked by a patient, self-controlled Brahmin—if then directed against a Brahmin of true brilliance—rebounds and is utterly extinguished, leaving not even the slightest remainder. The ethical point is that kṣānti (forbearance) and akrodha (freedom from wrath) in a Brahmin neutralize aggression, while anger-driven force, especially when turned against the truly radiant, destroys itself.
भीष्म उवाच
Anger-driven power is self-defeating: a Brahmin’s calm forbearance (akrodha, kṣānti) neutralizes hostile tejas/tapas, and any residual aggressive force, when turned against true spiritual brilliance, rebounds and is completely destroyed. The verse elevates self-control over retaliatory fury.
Bhishma is instructing on the dynamics of spiritual and moral power between social orders: the Kshatriya’s aggressive ‘fire’ (tejas/tapas used as force) is checked by a patient Brahmin; if the Kshatriya then tries to use what remains against a truly radiant Brahmin, that force is repelled and extinguished entirely.
