In the ancient history of our country India, it is written in the holy book Gita, that there was a fierce battle between the Kauravas and the Pandavas in the Mahabharata war to get the throne of the kingdom called Hastinapur.
Both of them were grandsons of the same clan and the same grandfather, among them Kourav had 100 brothers and Pandava's had only 5 brothers.
In this war, the main army from the Pandava’s side was Arjun, Arjun was a great archer, and no enemy could stand in front of him.
The day Arjun came to the battlefield, he saw that he saw only the brothers of his family all around the field. His mind got distracted and he thought in his mind that how he would use weapons on his own brothers.
His dilemma was understood by the charioteer of his chariot because he was none other than Lord Krishna himself, who was on the side of the Pandava in the war of truth over untruth, but since he was a god, he himself could not fight only them. He was giving his mental support.
Lord Shri Krishna understood Arjun’s dilemma and said to him, O Arjuna, all are brothers in this world, at this time do your work, don't worry about the result, because work is important.
So don't turn your head here and there only to see who is fighting against you in this war, your only job is to eliminate your enemies whoever they are.
