In the Mahabharata, the story between Karna and Kunti was one of the most moving. Krishna asks Kunti to meets Karna and reveal the truth about her love for him and how she had abandoned him in the river when she was just a young girl. Karna had already been told by Krishna that Kunti was his mother, but still he broke down in tears wanting to feel Kunti’s motherly love and affection after so many years.
Kunti feared the death of the Pandavas and since Karna was the true heir to the throne she tried to convince him to change sides, but Karna was a true Kshatriya and remained loyal to the one who gave him shelter, Duryodhana.
