Arjuna (Sanskrit: अर्जुन, IAST: Arjuna), also known as Partha and Dhananjaya, is the central protagonist of the  epic Mahabharata. In the epic he is the third of five Pandava brothers, from the lineage of the Kuru. In the Mahabharata War, Arjuna was a key warrior from the Pandava side and killed many warriors, including his elder brother Karna and grandfather Bhishma. Before the beginning of the war, his mentor Krishna gave him the supreme knowledge of the  Gita to overcome his moral dilemmas.
