In this poignant episode, long-held secrets come to light as Kunti meets Karna on the banks of the Ganga. With trembling voice and teary eyes, she reveals the truth he never knew—that she is his mother, and he is the eldest of the Pandavas. The revelation shakes Karna, but his loyalty to Duryodhana remains unbroken. With dignity and pain, he refuses Kunti's plea to join the Pandavas, yet makes a solemn vow: he will not harm any of her sons—except Arjuna, his sworn rival.

As Kunti walks away, heart heavy, returning to Vidura’s house, the heavens prepare for another test of Karna's spirit. Indra, Arjuna's divine father, arrives in disguise as a brahmana. He asks Karna for the very things that protect his life—his divine armour and earrings. True to his nature, Karna does not hesitate. He cuts them from his body and gives them away, bleeding but proud. Moved by this ultimate act of charity, Indra blesses him with the Ekaastra—a divine weapon that can be used only once.

A tale of silent love, unwavering loyalty, and the nobility of sacrifice—this episode reveals the depth of Karna’s character and the tragedy that shadows him.
