to which parva of mahabharat does gita belong
Bhishma Parva This book of Mahabharata includes the widely studied Bhagavad gita, sometimes referred to as Gita, or The Song of the Lord, or The Celestial Song. Bhagavadgita chapters describe Arjuna's questioning the purpose of war, ultimate effects of violence and the meaning of life.[7][8] Arjuna's doubts and metaphysical questions are answered by Krishna.[9] Other treatises in Bhishma parva include the Just war theory in ancient India,[10] as well as strategies of war and troop deployment.This book describes the deaths of Uttarā kumarā (brother-in-law of Abhimanyu and brother of Uttara wife of Abhimanyu), Vrishasena (Elder son of Karna) and also Bhishma's fall respectively on 1st, 3rd and 10th days of the war. Karna didn't fought in these first ten days on Bhishma's order.
Jarasandha According to the Hindu epic Mahabharata, Jarasandha (Sanskrit: जरासन्ध) was the king of Magadha. He was a descendant of King Brihadratha, the founder of the Barhadratha dynasty of Magadha. He was also a great devotee of the Hindu god Shiva. He was a great senapati and a Maharathi, but he is generally held in a negative light owing to his enmity with the Yadava clan in the Mahabharata.
