Q82. Does Krishna ask Arjuna to fight?

Yes. “Always think of me [Krishna] and at the same time do your duty of fighting. Surrender your mind and intelligence unto Me and surely you will attain Me without a doubt.” (Lord Krishna, Bhagavad-Gita 8.7)

Lord Krishna is asking Arjuna to do his duty of fighting, because Arjuna is a soldier in the military and thus it’s his job to fight when there is a war. For the civilians (those not in the military), we must do our duty according to our occupation and at the same time think of Lord Krishna. Lord Krishna told Arjuna to fight because the other side wanted war and they were the bad guys. When there are two sides, with one side wanting war, then there will be war and thus Lord Krishna asked Arjuna to fight and destroy the bad guys. Arjuna and his followers were good and on the opposing side were the bad guys. However, all the soldiers on both sides who died in the war got immediate liberation. This is because anyone who is killed in front of Lord Krishna or by Him, gets liberation. This is how merciful Lord Krishna (God) is.
