I saw in all the major shows. When Bheeshma was on his death bed. Karna went to meet him. He bowed to Bheeshma. They talked for a while. Karna asked why didnt Bheeshma join the fight from day 1. To which Bheeshma said he knew that Karna was Kunti's son. And he wanted to avoid the conflict of the real brothers as much as possible. Now here's where my doubts arise. 1. Did Bheeshma really know the truth about Karna? (I dont think so, correct me if I am wrong?) 2. If there is a reference to the above in our texts then why didn't he reveal this truth may have avoided the war. (Again my thought) 3. Would it have a different result to the war if Karna joined the war? (I don't think so this too.) Some say the tv shows show alot of wrong stuff I hope this isn't wrong.
