one dialogue of Duryodhana in SECTION LXI of UDYOGA PARVA - "The gods attained to their divinity for absence of desire, covetousness, and of enmity, as also for their indifference to all worldly affairs. Formerly, Dwaipayana-Vyasa and Narada of great ascetic austerities, and Rama, the son of Jamadagni, told us this. The gods never like human beings engage in work, O bull of the Bharata race,from desire, or wrath, or covetousness, or envy. Indeed, if Agni, or Vayu, or Dharma, or Indra, or the Aswins had ever engaged themselves in works from worldly desire, then the sons of Pritha could never have fallen into distress. Do not, therefore, by any means, indulge in such anxiety, because the gods, O Bharata, always set their eyes on affairs worthy of themselves."
This dialogue not only shows Duryodhana's disbelief in the God-fathers' of the Pandavas, but also opens up new possibilities. It is very interesting that Duryodhana does not mention "Surya", but mentions "Agni!" Now, in the Rig Veda, Agni is often synonymous to Angiras, and Angirasas are often addressed as Demi-Gods!
Duryodhana's mention of Gods - Agni, Vayu, or Dharma, or Indra, or the Aswins - takes the number to six'! Did he know that Kunti had another child born before her marriage, though he certainly did not know who he was? So, we can guess, there were speculations doing the round about Kunti's pre-marital affair' and her lost child.' That Kunti's secret became an open secret' is probable given the fact that she lived with the maidens! Women were perhaps, already cursed before Yudhishthira cursed Kunti - henceforth no woman shall succeed in keeping a secret.' (SECTION VI, SHANTI PARVA) It was known to Duryodhana then, that Kunti had a son by one Angiras! What a shock would it have been for him to learn that his strongest ally and friend was indeed that lost child!' Destiny spared him that shock!
Perhaps, Karna too knew about Kunti's affair' and her lost child,' though he could not be certain whether it was himself, until Krishna confirmed his idea! That is why when Krishna tells him that he was indeed Kunti's son, Karna replied (SECTION CXLI of UDYOGA PARVA) -" 'Without doubt, O Kesava, thou hast said these words from thy love, affection, and friendship for me, as also in consequence of thy desire of doing me good, O thou of Vrishni's race. I know all that thou hast said unto me. Morally, I am the son of Pandu, as also in consequence of the injunctions of the scriptures, as thou, O Krishna, thinkest. My mother, while a maiden, bore me in her womb, O Janardana, through her connection with Surya. And at the command of Surya himself, she abandoned me as soon as I was born. "
Karna's version of the story throws a new light to what we knew so far! Karna is confident of his version that Kunti abandoned him at the command of Surya himself! So, had Karna been misbehaving with the Pandavas so long only to force Kunti to come out with the Truth?
Now, to my second focus of discussion - Why Kunti had sex with this man? Or why was she attracted to him? Was she raped?
In the SECTION XC of UDYOGA PARVA, Kunti laments In the matter of my present sorrows, however, I blame neither myself nor Suyodhana, but my father alone. Like a wealthy man giving away a sum of money in gift, my father gave me away to Kuntibhoja. While a child playing with a ball in my hands, thy grandfather, O Kesava, gave me away to his friend, the illustrious Kuntibhoja'.
This shows her great sorrows at not having got the warmth of love from her real father. Her referring to Kuntibhoja as Kuntibhoja', and not as father', shows her cold formal relationship with him, as also her disgust for him for having thrown her into such a predicament!
So, Kunti had to abandon the child under duress. Didn't she protest? Well, perhaps! But, in Kunti, fear' always pre-dominates her maternal instincts! When fear' is in, maternal instinct' is out! We have at least another clue in support of this. In SECTION CXXIII of ADI PARVA, one day after Bhima was born; he was sleeping in Kunti's lap. He fell from the lap because Kunti, frightened by a tiger, had risen up suddenly, unconscious of the child that lay asleep on her lap. And as she had risen, the infant, of body hard as the thunderbolt, falling down upon the mountain breast, broke into a hundred fragments the rocky mass upon which he fell.' Our attention is taken away by Bhima's strength! But isn't it natural, we may ask( and never can be sure!), that Kunti should have grasped and clasped Bhima deep into her breast instead of causing him fall being unconscious of the child that lay asleep on her'? A motherunconscious of her child! -
From his father's side, Karna is always already' a Puru!Karna has Bharadwaja-Angira blood in him just like Bhisma and Drona! That explains, other than why all three fought for the Kuru-side (though Bhisma has an exceptional motive!), Karna's importance to the Kuru-side, Drona's breaking of nations' of Panchala, as well as the causes of marginalization of Bhisma in Hastinapura politics!The Kuru-war hides beneath its Khshyatriya garb a war of the Brahmanas, with liberal-cosmopolitan-Samannbyapanthi Vashishtha-Bhrigu-Certain break-away Angira gotras like Kanva, Ghora and Garga Angiras alliance under Vyasa's leadership on one side, and the orthodox Bharadwaja-Gautama Angiras on the other!Bhisma Parva, Drona Parva and Karna Parva were re-written by latter Bharadwaja-Gautama Angirasa poets, to malign Krishna and Arjuna, by the re-creation of mythical propaganda that Bhisma, Drona and Karna were killed in Adharma Yuddha,' by Krishna's immoral cunningness!
