Bhaṭṭikāvya 2.35

2.35

dharmo'sti satyaṃ tava rākṣasā'ya- manyo vyatiste tu mamā'pi dharmaḥ,
brahma-dviṣas te praṇihanmi yena, rājanya-vṛttir dhṛta-kārmukeṣuḥ.

“This duty of yours is true, O demon, but another, reciprocal duty belongs to me as well,
by which I, observing the conduct of a warrior, holding bow and arrows, strike you down, the enemies of the sacred order!”
