"Really?!"
It was Gandhari who spoke up first with an excited voice, She was surprised that Rishi Durvasa offered to teach Karna, He never taught anyone else yet.
Though Gandhari didn't know the reason why Durvasa but others in the room knew why Durvasa never had any students but who is Gandhari? All she is good in people, In her eyes Durvasa just like she is a big devotee of Lord Shiva, It would be great if Karna learn from him.
She didn't show it before but she was very sad hearing Karna's words about how no one will teach him. At that time she thought no one dared to defy the orders of the empress, If she ordered there would be rows of sages ready to tea h karna.
But then she heard Karna's argument, Yes she can make others teach him but she can't make sure they will teach him right. She knows a golden rule : It's better to be ignorant than the lord of incomplete knowledge.
Because ignorance will not be going to harm you as much as the use of incomplete knowledge, ignorance can be forgiven as it was done unknowingly but using incomplete knowledge is nothing but an arrogant thing, One of the most hated things at this time.
She was sad knowing Karna can't able to find a teacher, though he said he can go to Surya Deva but Gandhari didn't take that to heart as to how can Surya Deva ever teach the son of a mortal?
No matter how unbiased Surya Deva is he is still a celestial deity bound by celestial laws and duty, She is sure at best Surya Deva just like her can recommend Karna another Guru but can't teach him.
But now there is nothing to worry about, A rishi Durvasa decided to teach Karna, He is known in the world as unbiased, So he did not going to care about the Varna (Caste) of Karna.
He will teach Karna fairly and justly like a real Guru should.
Durvasa heard the excited voice and Gandhari smiled. Yes of course it is the thing to be excited about, He never takes any student under him, Karna being his student is a big deal.
Duryodhana and the other kids do not know many details, So they thought this is a good thing for Karna, Hence they were happy for him except for two people, Ellavaya and Vikrama.
Both kids were looking in fear towards Karna as they knew being a student of Durvasa meant dancing on the edge of the sword. One wrong move and you are done.
"*Ahem* Sage Durvasa, Angaraj (King Of Anga) is still a little kid. Why don't we wait till he grows up before asking him this question? I sure heard he wants to be taught by Surya Narayana, It's not right to ask this question now, Right?"
Suddenly a very cunning voice interrupted the conversation, The beloved and Infamous Mama (Uncle) came to the rescue, Shakuni came in front and quickly said the words that came to his mind.
To be honest, He knows this is a foolish thing to do. Only a madman will think of standing in front of someone like Rishi Durvasa and trying to debate with him, at that point, you are just asking to be cursed.
But he had to, He owed that to Karna, Now not only to rescue his sister from the dark world of hers but now also to show him the mirror, Pulling the cloth of hatred and revenge which was blinding him from his eyes.
So when though his whole being yelled at him not to do it, He still did it as a debt can never be left unpaid, He is Kshatriya (warrior) after all.I think you should take a look at
Karna here signed in relief when he saw Shakuni come in front of him to save him, This guy didn't even need to be told and said quite a reasonable argument.
Warfare training starts at the age of 10, Before that is Vedic (Text) knowledge, Which though mostly done by the teacher but can be taught by parents, So it's very hard to argue comment.
Well, there are a few loopholes here and there but seeing it was dropped at a moment solution, It's perfect. No wonder why this guy can let all kings all over the Aryavart work for his revenge.
Indeed a fearsome intelligence, If used for the right cause can be unstoppable, Karna just hopes this can be considered the right cause in the eyes of the world.
Others like Gandhari and the Kids were confused by Shakuni's action, Gandhari was even angry as she thinks Karna finally found a good teacher and now her brother is messing with it.
If she does not know that her brother never does anything without a reason, She until now has interrupted and said something in favour of Karna being a student of Durvasa.
The only others who were happy that Shakuni interfered were the Surya family and Vikarma and Eklavaya. They understand what it means to be a student of Durvasa.
Even if Vikarma and Eklvaya didn't know much about Rishi Durvasa, What they know and saw is enough to come to that conclusion.
"HOW DARE YOU!? Who gives you the right to speak in front of me? And that too in the matter of me and my soon-to-be student? This much insolence, The audacity of yours, I Shiva ansha (Part Of Shiva), Son of Atri (father) Anasuya (mother), The Durvasa cur-"
"I can accept to be your student but I have a few conditions."
The argument of Shakuni was quite good but as said before the problem was the well-started argument can be only used against the man who follows the same rules.
Unfortunately, Rishi Durvasa did not come in the group of those men, He as expected became extremely angry at Shakuni for even questioning him, and as anyone who knows a little bit about him, When he became angry he was ready to curse.
But Karna can't let that happen, Not only Shankuni is the best thing he can use against those ingenious blue guys*, But also because Shakuni stands for him, He can't watch him get cursed in front of him.
(A/N : Blue guys : As said before Karna didn't know there is only one Shri Krishna, He misunderstood Keshava and Madhava as different people even though they were other names of Shri KrKrishna
As for blue? He only saw Shri Krishna as a blue person, He didn't know his actual skin colour was as dark as rainy clouds, hence blue guys, Hope this solves your question, If not feel free to ask me.
Like always thank you for reading and have a good day ?.)
