Tell me who are You in such a fierce form? My salutations to You, O best of gods, be merciful! I wish to understand You, the primal Being, because I do not know Your mission.
The Supreme Lord said: I am death, the mighty destroyer of the world, out to destroy. Even without your participation all the warriors standing arrayed in the opposing armies shall cease to exist.
Therefore, get up and attain glory. Conquer your enemies and enjoy a prosperous kingdom. All these (warriors) have already been destroyed by Me. You are only an instrument, O Arjuna.
Bhagavad Gita, chapter 11, verses 31-33
“Victorious warriors win first and then go to war, while defeated warriors go to war first and then seek to win” ― Sun Tzu, The Art of War
