In Mahabharata The great Epic Of India during The Kurukshetra War The Conversation Between Arjun The Great Archer Warior, Son of Pandu and His Charioteer, The Lord Shri Krishna is Depicted in Shrimad Bhagbat Geeta.
I Translate The Sanskrit and Hindi Version to English to My Own Way.

Arjun: He is very much sad when he see that all of his enimies in this Kurukshetra war are his relatives duryadhan and his brother, his repected elders like Vhisma Pritamaha, kripacharya, his teacher Guru Dronacharya. So he Left his Bow to Ground and ask Lord Shri Krishna to help him find a way.
Krishna: Krishna telling him in this war like situation your behaviour is so foolish. This is not a realistic behaviour of Knowledgeable Warior like you. You get nothing with this only be blammed.
He tells to Arjun don't be impotent, don't be sentimental and stand up for fight against your enimies.

Arjun: He tells to Lord Krishna that he can't fight with his great teachers and his brothers. He tell again he don't know what to do. He ask Lord Krishna to show him right path in this war Frontier. He tells he don't want fame, Kingdom and wealth if this come from killing his uncle brothers and my respectable teachers though they are his enimies now. He then silent.

Krishna: He loughs at him then tell him that he is mourning for those people who are not eligible for that. True Knowledgeable person never mourns for anybody even for dead people.

Krishna: He tells that he is always be here and Arjun and all other opponent kings are also always there. And Every body here Remain in Future also.
He tells that human souls grow younger from childhood and then become older in human body. Body dies only but Soul Remains and its take another body. With the transformation of life Soul going to leaving its ignorance.
Lord Krishna tells Arjun that happyness and sorrow is not stable in life it is like hot and cold feelings by our sense organs which is not constant. He tells Arjun that we have to be patience enough to bear all these agony.
Lord Krishna tells Arjun that The man who feels equally in happyness and sorrow be calm in both the situation equally is eligible for freedom from the circle of life.
Lord Krishna tells Arjun that there is no real existence of body in Universe and our soul is unique and remain unchanged.
Lord Krishna tells Arjun that no one in the universe is able to damage the soul.
Lord Krishna tells Arjun that The universal soul reside in the body of all human beings and the body dies only. These soul is unchanged Remain immortal.So he tells Arjun that he must go for war against his enimies who stand in the warfront against him.

Lord Krishna tells that who thinks that he going to kill those soul or the soul is died, those mans are very fool, not have true knowledge. The soul is not killing Anybody and the soul never died.

Lord Krishna tells that The soul is never take birth in past, not present and not in Future also. The Soul is unborn entity.
Lord Krishna tells Arjun that the man who thinks that the soul is unborn, universal, unchanged, undamagable entity then how that man can kill Anybody and nobody can kill that man also.
Lord Krishna tells Arjun that like the way we changed our old cloth and wearing a new cloth, the same the soul also change old unsuccessful body and take a new one.
Lord Krishna tells Arjun that that no weapon can hurt the soul, the fire can burn the soul and the water can not wet the soul and the air can not dry the soul. The soul is unique, universal and always remain unchanged.
Lord Krishna tells Arjun that if you think that the soul is invisible, unique, universal and always remain unchanged then you don't need to worry about it don't feel mourning.
Lord Krishna tells Arjun again that if you thinks that the soul is always taking birth and always died then also you don't need to worry about it and don't feel mourning, because in this universe those who take birth he must die one day and it is predecided, and the soul takes rebirth again.

Lord Krishna tells Arjun again all living beings are unseen before birth and after die they are become invisible, we can only see them in-between the birth and death. So we dont need to be panik About it.
Lord Krishna tells that some of think the soul as unbelievable entity, some of us described the soul as a unbelievable entity and some of them hear about it but don't understand the soul at all.
Lord Krishna tells Arjun that you can't kill the soul in body. So don't need to be panic about it.

Lord Krishna tells Arjun that You are a warrior and you have to fight the war for royalty and for establishing law and order in its right place. To Fight here is very greatest job.
He speaks to Arjun that you are so luck person that you get the opportunity for fight for truth, and reality. World you give you very honour for fighting against unrighteousness.
He speak to Arjun that if you not fighting the war for establishing righteousness, then people will defame you and deserve a sin.

He speaks to Arjun that people describe your defamity for a very long time. As you are very honourable person this defamity is like a death for you.
He speaks that if you don't faught the fight now those people and the other warrior thinks you before a great warrior, now they think that you leave the war as you are afraid of death and you have no courage at all.

He speaks to Arjun that if you die in the war then you go to the heavens and people remember your bravery and courage always and if you get victory in the war then get the kingdom of Earth and wealth everything you want.

He speaks to Arjun that don't think about happyness and sorrow, victory and defeat about the war just faught the war because it is your duty and if you do this no sin touch to you.
