7.45.1

उभा जिग्यथुर्न परा जयेथे न परा जिग्ये कतरश्चनैनयोः ।
इन्द्रश्च विष्णो यदपस्पृधेथां त्रेधा सहस्रं वि तदैरयेथाम् ॥ ७.४५.१ ॥

Both have won; neither is defeated, nor is either of the two defeated at all. O Viṣṇu, when Indra and you contend against each other, you two scatter that thousand in three ways.
