This Karna is neither a Rathi nor an Atiratha in battle. Though ever generous he has been deprived of his celestial earrings. All this is owing to the curse of Rama (his preceptor) and the words of a Brahmana.
एष कर्णो न चाप्यतिरथो रणे। वियुक्तः कवचेनैष सहजेन विचेतनः॥ कुण्डलाभ्यां च दिव्याभ्यां वियुक्तः सततं घृणी। अभिशापाच्च रामस्य ब्राह्मणस्य च भाषणात्॥
