अपि ब्रह्मवधं कृत्वा

अपि ब्रह्मवधं कृत्वा प्रायश्चित्तेन शुध्यति।
तदर्थेन विचीर्णेन न कथञ्चित् सुहृद्द्रुहः॥२९८॥
—मित्रभेदः नाम प्रथमे तन्त्रे चण्डरव नाम शृगाल कथा कथा १०
api brahmavadhaṁ kṛtvā prāyaścittena śudhyati|
tadarthena vicīrṇena na kathañcit suhṛddruhaḥ||298||
—mitrabhedaḥ nāma prathame tantre caṇḍarava nāma śṛgāla kathā (kathā 10)
Even after killing a knowledgeable person (or a brāhmaṇa), one might purify by [an appropriate] expiation.
But having gone through that even, there is no pardon for one who betrays a friend.


गवार्थे ब्राह्मणार्थे च

गवार्थे ब्राह्मणार्थे च प्राणत्यागं करोति यः।
सूर्यस्य मण्डलं भित्त्वा स याति परमां गतिम्॥४५३॥
—मित्रभेदः नाम प्रथमे तन्त्रे कथा २३
gavārthe brāhmaṇārthe ca prāṇatyāgaṁ karoti yaḥ|
sūryasya maṇḍalaṁ bhittvā sa yāti paramāṁ gatim||453||
—mitrabhedaḥ nāma prathame tantre kathā 23
For the sake of a cow, or for a brāhmaṇa, One who sacrifices his life.
Having attained the realm of the Sun God, he attains the highest state!

Cf. this with the oft-(mis?)quoted statement of Mahatma Gandhiji, that in self-defence, you can even kill a cow (it is ugly to even type this) that comes to kill you. Cows are among the most sāttvic creatures, and unless brutally provoked, I can’t see why they would turn violent. Of course, they can turn mad, if fed with slaughterhouse waste. Rāmāāāāāāā!!

Isn’t there a limit to how much man can play with nature?
