Why did Parashuraama teach Karna?

[Shri Manikanta asked: Pādanamaskāram Swamiji, Why did Parashuraama Prabhu gave teaching to Karna even though He knows everything. Kindly please enlighten me on this. Pādanamaskāram Swami.]

Swami replied: Every actor in the drama knows that his dialogues are not true, but speaks as if true. Similarly, in the divine drama also, actors speak.
