Bhagavad Gita

Arjuna doesn't want to fight. He doesn't understand why he has to shed his family's blood for a kingdom that he doesn't even necessarily want. In his eyes, killing his evil and killing his family is the greatest sin of all. He casts down his weapons and tells Krishna he will not fight. Krishna, then, begins the systematic process of explaining why it is Arjuna's dharmic duty to fight and how he must fight in order to restore his karma.
