Mahabharat: How Kripacharya and Dronacharya became the gurus of Kaurava-Pandavas?

One day King Shantanu went to the forest for hunting. There he saw a boy and a girl. Both of them had bows and arrows and their bodies were shining brightly. The king was surprised to see this wonderful scene and brought those children with him to Hastinapur.

King Shantanu brought up both the children in the royal palace like son and daughter. They were provided with the best education, security and all facilities. With time both started growing up. Seeing his intelligence and brilliance, the royal family and the people of the court also started getting impressed.
