स्वधर्ममपि चावेक्ष्य न विकम्पितुमर्हसि।
धर्म्याद्धि युद्धाछ्रेयोऽन्यत्क्षत्रियस्य न विद्यते।।2.31।।
2.31 Even considering your own duty you should not waver, since there is nothing else better for a Ksatriya than a righteous battle.
2.31 Further, even though there is killing of life in this war which has begun, it is not fit for you to waver, considering your own duty, as in the Agnisomiya and other sacrifices involving slaughter. To a Ksatriya, there is no greater good than a righteous war, begun for a just cause. It will be declared in the Gita: Valour, non-defeat (by the enemies), fortitude, adroitness and also not fleeing from battle, generosity, lordliness - these are the duties of the Ksatriya born of his very nature. (18.43). In Agnisomiya etc., no injury is caused to the animal to be immolated; for, according to the Vedic Text, the victim, a he-goat, after abandoning an inferior body, will attain heaven etc., with a beautiful body. The Text pertaining to immolation declares: O animal, by this (immolation) you will never die, you are not destroyed. You will pass through happy paths to the realm of the gods, where the virtuous only reach and not the sinful. May the god Savitr give you a proper place. (Yaj. 22.214.171.124). Likewise the attainment of more beautiful bodies by those who die here in this war has been declared in the Gita, As a man casts off worn-out garments and takes others that are new ৷৷. (2.22). Hence, just as lancing and such other operations of a surgeon are for curing a patient, the immolation of the sacrificial animal in the Agnisomiya etc., is only for its good.
