He sees that some among his enemies are his own relatives, beloved friends, and revered teachers. He does not want to fight to kill them and is thus filled with doubt and despair on the battlefield.[106] He drops his bow, wonders if he should renounce and just leave the battlefield.[105] He turns to his charioteer and guide Krishna, for advice on the rationale for war, his choices and the right thing to do. The Bhagavad Gita is the compilation of Arjuna's questions and moral dilemma and Krishna's answers and insights that elaborate on a variety of philosophical concepts.
