The question is, difficult to answer because many assumptions are to be made and beyond the least knowledgeable person like this answerer. The following is given for thought which is based on Vyasa Bharata 1) Bhagavad Gita to Arjuna, by boon to Sanjaya and Dhritarashtra: Nobody talked on Bhagavad Gita at any other time except by Arjuna who wanted to hear again but the request was rejected by Lord Krishna! (Mahabharata, Book 14: Aswamedha Parva, Chapter 16, Anugita Parva).
Lord Krishna felt sad on this forgotten aspect. But instead Lord Krishna gave one Anugita. http://www.sacred-texts.com/hin/m14/m140... Lord Krishna gave Srimad Bhagwad Gita only to Arjuna and the entire world was in suspended animation at that time.
Only exceptions were Sanjaya and through him Dhritarashtra. The Bhagavad Gita portions are in fact a live running commentary by Sanjaya to Dhritarashtra. The author Sri Vyasa in Mahabharata gives Bhagavad Gita to us through Sanjaya only.
2) Barbarika, son of Ghatotkacha Barbarika name and the episode is not mentioned in Mahabharata. This may be from some other version or from a folk base. In Rajasthan, he is worshipped as Khatushyamji, and is believed to have been sacrificed before the Mahabharata war to ensure the victory of his grand-fathers, the Pandavas.
In return for his sacrifice, he was deified by a boon given by Krishna. There is paradox here. He wanted to fight for the loosing side and took his life for the victory for the Pandavas.
Five thousand years ago, when Arjun refused to fight the upcoming battle at Kurukshetra, Krishna overcame Arjun’s reluctance to fight by analyzing the idea of the self, and showing that the man is in error who thinks that he is doing this, that or something else. And when it is found that what Arjun calls “I” is a sort of fiction created by avidya, his own metaphysical ignorance, a great part of difficulty ceases to exist. Krishna further proceeds to demonstrate the existence of a higher individuality, of which Arjun had no previous knowledge.
Then He points out that this individuality is connected with Parbrahman, the Causeless Cause or the First Cause of the Western world and goes on to describe the Nature of Parbrahman and says that It is none other than His avaykta form. In order to make him firm of purpose, Krishna gives Arjun further teachings on the battlefield. However, for our benefit, Sanjaya, the counselor and charioteer of the blind king Dhritraashtra, with antenna raised in the ‘line of sight’ of the battle, received a clear video and an audio signal from Kurukshetra.
Arjun: “If we fight, will it not result in the destruction of Dharma, that is, virtue, duty and moral action.” Krishna: “At first, you are not even ready to fight this righteous war and yet, you ask what would happen to Dharma. In my judgment, Dharma will be lost any way.”
Arjun: “dharme nashte kulam kritasnam- dharmo-abhibhavatyut…This war will result in vitiation of women and in the admixture of castes by which the manes and their races will fall; social virtues and family merits will also be ruined.” Krishna: “utseedeyurime lokaa na kuryaam karma chedaham…Have you ever consideredwhat might happen if I don’t perform my duty conscientiously? I shall be the cause of confusion of the social norms.
The admixture of castes will be caused even without waging the war and I will still be held responsible for it.” so, arjuna in dilemma asking question and Bhagwan Krishna clearing the doubts and in fact, Bhagwan is taking much effort to bring arjuna to the battle field. From the above Gita is a conversation between Arjuna and Bhagwan Krishna. This conversation was directly relayed to Dritarashtra by the chariotor of Dritarashtra named Sanjaya.
Sanjaya a trusted servant of the King. A servant did the work what the master ordered. Taking a family, the family secrets are known to cook, gardener and driver.
So, here the driver sanjaya luckily had the opportunity to see and hear Bhagavat Gita which he transformed to King Dritarashtra.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
