karna

Let us come one by one to your points.

first of all Acharya Madhva is incarnation of Hanuman only ,he has not descended from moolroopa of Vayu.

Bhagavdgeeta mentions Duryodhana speaking about karna as from his side to his preceptor and not being present in the army.[he was always accesible to the Kauravas in case bheeshma fell early to take over the reins]

Shalya takes on the mantle as sarathi only when Karna is appointed as Commander in Chief. that was after Bheeshma fell to the arrows of Arjuna.Karna was decisively not on the battlefield as he was addressed as Ardharathi . Bheeshma wanted to save him for the last.

Shalya himself was decietfully taken on Duryodhana’s side, upon that a great warrior like him was made to be charioteer to Karna ,only to psychologically elevate him to equal Arjuna. is there any comparision between Arjuna’s charioteer [Lord Krishna ] and Shalya ,shalya himself was averse to the idea, Karna persisted only out of ego.He deserved discouragement thus.

everyone praised Karna, Karna was incarnation of Soorya [a divine] hence he had some devata like qualities and valour [not equivalent to arjun] ,these were definitely praised [every good man praises whatever little good others have,this is greatness of the good Bheeshma others ,not Karna].But Karna also had the presence of daitya suryavarman ,here all his bad acts are attributed to this demon.

Karna was not the son of Pandu , thus Kingdom cannot be birthright.[just like kingdom was not birthright of Duryodhana ,even after being son of caretaker King Dhrutrashtra].
He was offered world to tempt him towards righteousness, The height of evil is they are intent on doing evil to Arjuna[friendship was his selfish aide].
a duty conscious man [if he was] then his primary duty was towards Lord Krishna ,which he could never think of , but he was prompt in quoting loyalty towards a evil duryodhana .[more than duty he was out to prove his greatness towards Arjun, which chance only Duryodhan could provide and not Krishna ]This is known as kapat in real world terms.

speciality is of Lord Parashurama that he taught these three BHeeshma ,Drona and Karna ,knowing that they would aide Duryodhan in garnering enough guts to wage war against Pandavas. Parashuram is lord all knowing ,yet he himself appointed these as guards for Duryodhan. this increases the emphasis of power fo pandavas.

Pandavas did not cheat Bheeshma Drona, Karna , they were already defeated all put together single handedly by Arjuna in Draupadi swayamvar, Viarat [Agyatvasa] Go samrakshana episode. where was Karna’s valour at that time , when ARjuna defeated him ,what about his Kavach Kunadal then] Arjuna proved outrightly he was great . Karna was only blabbering amassing pity over his birth ,and other misfortunes.
Brave dont lament over their misfortunes. Bheeshma and Drona were killed in a fashion not to attract sin on account of they being preceptors. [everything was done as suggested by Krishna]. Dronacharya had clearly mentioned to Duryodhana , I shall protect you along with my family ,i shall take to weapons even though being a Bramhin ,but know it firmly even I will not be able to save you from BHeema.

Karna was defeted even before Mahabharath war by Bheema , in rajasooya digvijaya. At that time Karna had Kavach Kundala.
He could have killed him with kavach kundal also , but that would amount to insulting donor of kavach kundal. and thus kavach kundal had to be begged ,to keep its honor not greatness of Karna.

Now your other points. [mishaps to karna]
1. God Parashurama gave shapa , God knew he was kshatriya [God knows everything] , thus he taught him, it was foolish of Karna to have thought that he has tricked God , and also he had lied that he was Bramhin, thus he was rightly cursed.

2.Curse of a Bramhin, killing of a cow cannot be accidental , nothing is accidental , his loss of respect towards god , mother ,brothers,father ,friends,everything has rightly come to him as a curse. misfortunes wait to occur for those who are headlong and anti God.misfortunes get avoided for those who respect preceptors,parents ,freinds and others who have done some good.

3.Karna gave daana only to keep up his vrata that he would donate everything asked for till he kills arjuna. [ordinary people do vrata to obtain wishes, Greats perform vrata for Pleasing Vishnu] . He gave away kavach kundala fearing vrata bhanga and subsequently defeat at the hands of Arjuna , not out of bravery or devotion . Kavach kundal were divine present from Sun , they had to be preserved ,Arjunas arrows would have destroyed it anyhow, that would have brougth disgrace to Sun as having given false promise . Thus Surya ’s words were upheld by INDRA. Karna was destined to die for siding with Duryodhana. NO pity for him.

4.A kshatriya wages war with full force ,no matter brother or enemy, Arjuna had more love towards Kauravas,thus refused to wage war, he was sermoned by Krishna to wage a war as duty. Karna even after revealing that Arjuna was younger brother ,could not suppress his jealousy , thus could not promise Kunti that he would leave Arjun. this shows he had no love ,he was fighting for his honor [to prove he was greatest dhanurdhar ,which he was never ,time had proved it again and again]

5.Kunti does not disarm him , she makes an attempt to save him from sin of killing his brothers who were righteous , mother always wants her sons to be on the right path. She asks him to refrain, he bestows her with a boon to spare[ this is karna's ego that he is capable of killing pandavas, thus he offers boon] KUNTI{Krishna} had attempted to save Karna ,Karna felt he was being pampered , a sign of durabhimana.if he was a saint he could have offered to spare Arjuna also ?why only four?

6.Those who have weapons , it is their management to use or misuse ,Karna has used Shakti on Ghatotkacha ,its his mismanagement of resources , what Arjuna has done for it. Pity had he not used shakti ,even ghatotkacha would have finished him[it means obvious] that means Karna without Shakti was no match for Ghatotkacha ,[a small warrior compared to Arjuna] , what this Karna would have fought Arjuna then without Shakti? your own illustration is proving Karna as an unfit warrior.

7.Arjuna had disarmed him totally , and refused to kill Karna, But it was Krishna who insisted to kill him as a punishment because Karna had killed Abhimanyu when he was disarmed.where was Karna’s valor when Abhimanyu was fighting , why he could not have killed him with his weapons on. Karna could not defeat even Abhimanyu with arms, Ghatotkacha by pure skill he had to use boons of INdra to kill them . He ran away from battlefield when Bheema attacked him. Was he a match to Pandavas. A cheat himself had died unworthily there is nothing wrong in it. [he had earned his skills by cheating, he lost it by cheating] You reap what you sow.

now do quote the verses from bharath or bhagavat where you can see karna having listened to Bhagavadgeetha [ and that barbareek].
I am not hurt a bit by your verdict , but amused as I am that the whole text appeared to you as without any source . The above words are of Srimad Poornapragnya teertha and not my imaginations.
