Bhagavad Gita · 11.33

तस्मात्त्वमुत्तिष्ठ यशो लभस्वजित्वा शत्रून् भुङ्क्ष्व राज्यं समृद्धम्।मयैवैते निहताः पूर्वमेवनिमित्तमात्रं भव सव्यसाचिन्॥

tasmāt tvam uttiṣhṭha yaśho labhasva jitvā śhatrūn bhuṅkṣhva rājyaṁ samṛddham mayaivaite nihatāḥ pūrvam eva nimitta-mātraṁ bhava savyasāchin

Therefore arise and attain glory! Conquer your enemies and enjoy a prosperous kingdom. These warriors have already been slain by me — you are merely an instrument, O ambidextrous archer.
