2.31 Api, even; aveksya, considering; svadharmam, your own duty, the duty of a Ksatriya, viz battle  considering even that  ; na arhasi, you ought not; vikampitum, to waver, to deviate from the natural duty of the Ksatriya, i.e. from what is natural to yourself. And hi, since that battle is not devoid of righteousness, (but) is supremely righteous  it being conducive to virtue and meant for protection of subjects through conest of the earth ; therefore, na vidyate, there is nothing; anyat, else; sreyah, better; ksatriyasya, for a ksatriya; than that dharmyat, righteous; yuddhat, battle.
