Mahabharata: Why did Duryodhana show 3 fingers to Krishna while taking his last breath? What did it mean

Mahabharata: In the Mahabharata, we must have heard the name of Duryodhana. Duryodhana received several proposals not to fight or stop the Mahabharata war. But he rejected all peace proposals. Even after the war was decided, he had a proposal to cancel the war in a cordial manner by talking to the Pandavas. Even during the war, after the casualties of a large number of people, they also got an opportunity to save the lives of other people by stopping the war peacefully. But the stubborn Duryodhana did not want to retreat under any circumstances, because he was confused that in the end he would win his army. But in reality he was defeated. While taking his last breath, he showed three fingers to Lord Krishna. What did these three fingers really mean?
Lord Krishna went to Duryodhana and asked him, "Do you want to say anything?" On this, Duryodhana said that he made three mistakes during the Mahabharata war. Due to these mistakes, he could not win the war and today he is in this situation. He said that if he had already known about these mistakes, he would have won today. Lord Krishna very peacefully asked Duryodhana about his mistakes, on which Duryodhana told him that his first mistake was that he chose Narayan's army in place of Narayan. He said that if Narayan had been towards the Kauravas, the result would have been different.
Why Duryodhana showed 3 fingers to Krishna while taking his last breath
Duryodhana's second mistake was that despite his mother's opposition, he went in front of him wearing a cloth covered with leaf. If he had become naked, no warrior could beat him. He said that the third and final mistake was that he entered the war for the last time. If he had gone earlier, he would have known some things before. Perhaps the life of his siblings and friends would be saved.
Krishna heard all the things about Duryodhana peacefully
Lord Krishna peacefully listened to all the things of Duryodhana. Then he said, 'The main reason for your defeat is your unrighteous conduct and snatching your own Kulvadhu. You have written your luck with your own deeds. This statement of Shri Krishna meant that Duryodhana lost not due to his three mistakes, but because he was unrighteous. Hearing this, Duryodhana repeated on his mistake.
