Arjun chose Krishna, though Krishna had vowed to lay down his arms on the battlefield ... ... Krishna asked: "Why did you pick me, knowing I would not fight?" "I can handle the soldiers myself, O Krishna, if I have your presence to give me moral support. Some of your glory will surely rub off on me."
Mahabharata
Truth, self control, asceticism, generosity, non-injury, constancy in virtue รณ these are the means of success, not caste or family.
