Shiva Purana
युद्धं पुण्यतमं स्वर्ग्यं रूपज्ञं सर्वतोमुखम् ॥ सर्वेषामेव वर्णानां क्षत्रियस्य विशेषतः ॥ ३३॥
A righteous war is conducive to the attainment of heaven. It is sanctifying. It makes known the multi-faced beauty of a man. This is the case with the people of all castes, particularly so in the case of a Kṣatriya.
english translation
