Your Brahma might is superior to his Brahma might though his is amited with his Kshatriya might. As I am interior (to Drona) in consequence of my having only Kshatriya might, therefore, give me your Brahma might.
ब्रह्मक्षत्रे च विहिते ब्राह्म तेजो विशिष्यते। सोऽहं क्षात्राद् बलाद्धीनो ब्राह्मं तेजः प्रपेदिवान्॥
