The Mahabharata epic opens its chapter on Surya by reverentially calling him the "eye of the universe, soul of all existence, origin of all life, goal of the Samkhyas and Yogis, and symbolism for freedom and spiritual emancipation". In the Mahabharata, Karna is the son of Surya and an unmarried princess named Kunti. The epic describes Kunti's difficult life as an unmarried mother, then her abandonment of Karna, followed by her lifelong grief. Baby Karna is found and then adopted, and grows up to become one of the central characters in the great battle of Kurukshetra where he fights his half-brothers.
