Karna was the disciple of which Guru? How could he become his desciple?

Answer 1

Parashurama Bhargava or Parasurama (Axe-wielding Rama), according to Hindu mythology is the Sixth avatara of Vishnu, belongs to the Treta yuga, and is the son of Jamadagni. Parashu means axe, hence his name literally means Rama-with-the-axe. He received an axe after undertaking a terrible penance to please Shiva, from whom he learned the methods of warfare and other skills.

In the Mahabharata, Parashurama was the instructor of the warrior Karna, born to a Kshatriya mother but raised as the son of a charioteer, or lower class of Kshatriyas. Karna came to Parashurama after being rejected from the school of Drona, who taught the five Pandava and one hundred Kaurava princes. Parashurama agreed to teach Karna, believing him to be of Brahmin birth, and gave him the knowledge of the extremely powerful Brahmastra weapon. But an incident would render the Brahmastra almost useless to Karna.

How he was exposed, means not a Brahmin is another story and will be naratted later when asked.
