this is what ur post says " And seeing that
in process of time his son had grown up,
Adhiratha sent him to the city named after the
elephant. And there Karna put up with Drona,
for the purpose of learning arms. And that
powerful youth contracted a friendship with
Duryodhana. And having acquired all the four
kinds of weapons from Drona, Kripa, and
Rama, he became famous in the world as a
mighty bowman. And after having contracted a
friendship with Dhritarashtra's son, he became
intent on injuring the sons of Pritha. And he
was always desirous of fighting with the high-
souled Falguna. And, O king, ever since they
first saw each other, Karna always used to
challenge Arjuna, and Arjuna, on his part, used
to challenge him."
that's why I was surprised. of dury and everybody knew him always then what was the drama at rangbhoomi?
