Drona: Drona was a Brahmanas. As per the Dharmashastras, it was the duty of the Brahmana to impart education. It was considered a pious deed of the Brahmanas. Drona was also following that system. He was imparting education. He taught archery to the princes of the Kuru Dynasty. In those days, people of low caste were not entitled to get education. Keeping this view in mind, Drona refused imparting education to Ekalavya. But in the course of time, Ekalavya learnt archery and acquired great skill. But Drona demanded right thumb of Ekalavya as his teaching fee. This was against religious norms. In fact, Drona did this just to ensure that no one could be better archer than Aijuna in the field of archery.
Hidimba: Hidimba was a lady demon, that is rakshasini. In fact, all the rakshasas were man-eaters. One day her brother asked her to catch Pandavas so that he may eat them. But Hidimba did not follow this. She fell in love with Bhima and married him. A rakshasa boy was bom to him, named Ghatotkacha. In this way, Hidimba did not keep ; the norms of rakshasas.
Matanga: Matanga was Boddhisatta who was bom in the family of a chandala. But he married Dittha Mangalika who was the daughter of a merchant. A son was bom to him named Mandavya Kumara. In the course of time he learnt three Vedas. He used to offer food to sixteen hundred Brahmanas every day.’But when his father appeared before him dressed in rags with a clay alms bowl in his hand, he refused to offer food to him. The reason was that, he considered his father as outcaste and his food was meant for Brahmanas only. Matanga advised his son not to be proud of his birth. After saying this, he disappeared into the air. When Dittha Mahgalika knew this incident, she went after Matanga and begged his forgiveness. This way acted like a true wife. She performed her duty religiously. A donor is considered generous. But Mandavya failed to follow the norms of religion and generosity.
