Karna tells Krishna “lot of unfairness has happened to me. Is it my fault that I am born illegitimate? My mother left me the moment I was born. I , who should have been brought up in palace was brought up in ‘sutha’s house. I did not get full education (in war science) from Dhronacharya because I was considered as a ‘sutha’. Even though Parasurama taught me full, he gave me a curse that I should forget everything , since I was a kshatriya. Is it my fault. I didn’t even know I was a kshatriya. Some boy came running and was hit by my chariot. It was not my fault, it was an accident. Even then the boy’s father cursed me. Even in Draupadi’s ‘swayamvara’ I was disgraced for being a ‘sutaputra’ even though I was the ‘suryaputra’.

Kunti had affection only for her other children. She never told me the truth and finally when she did tell me , she asked me not to use any weapon on her son’s second time. Even though she never behaved like a mother , I gave her whatever she asked. I should have got the throne of ‘ Kurukula’but am ruling a kingdom I got out of Dhuryodhana’s charity.
Bhishma never gave me any respect as a worthy person and he also disgraced me and disallowed me to fighting in the army under his Generalship.
I am beating all this due to friendship of Dhuryodhana. You all might think that he is a villain, but he has done only good to me.  Even when Gods left me Dhuryodhana stood by me. So what is wrong in my being in his side. ”
Krishna answers.
“Karna, I was born in a jail. Death was waiting for me even before my birth.
The night I was born I was separated from my mother. At least you had some education in ‘sutha’ house.
From childhood you grew up hearing the noise of swords, chariots, horses,bow and arrows.
For me I got only cow herd’s shed. No swords, no chariots, but only cattles, cow dung, milk maids with attempts on my life by Kamsa.
No army, no education. In young age I was accused of killing my own uncle. In fear of Jaradandha I had to move my whole community from the banks of Yamuna to far off Sea shore a very new place.
I could hear people saying I am the reason for all their problems. I was also called a coward for running away. When all of you were being appreciated for your valours by your teacher (guru) I had not even joined a Gurukula. I joined the gurukula of Rishi Sandipani only at the age of 16. You have a kingdom, but what about me. When girls whom I don’t even know, want me to protect them by marrying them I have to rush there leaving whatever I am doing. I never got the girl I loved but any one who loves me , get me.
If Dhuryodhana wins the war you will get lot of credit and will become more famous. I am just a Sarathi ( charioteer). What do I get if Dharmaraja wins the war? Already I am being blamed for the war and all problems. This blame will not vanish if Dharmaraja wins or loses.
Remember one thing Karna. Everybody has challenges in life. LIFE IS NOT FAIR ON ANYBODY. Dhuryodhana has lots and lots of unfairness in life. So also Yudhishtra.
But what is Right (Dharma) is known to your mind ( conscious). How much unfairness we got, how many times we were disgraced, how many times we were denied what is due to us, is not important.
What is important is how you REACTED at that time decides your personality. Stop whining Karna. Learn to walk in the path of consciousness ( विवेका). Life’s unfairness does not give you license to walk the wrong path (अधर्मा)
