During the Pandavas’ exile, the sage Markandeya told them a story about the brahmin Kaushika. Kaushika once meditated under a tree. A bird came and sat down on a branch and excreted on the sage’s chest. The sage was furious and turned the bird into ashes. But instantly he felt remorseful . He decided to spend his life begging on the streets. He once reached a brahmin household and the brahmin woman asked him to wait for a while. The master of the house reached there then, and the woman forgot about Kaushika. Kaushika spoke angrily to the woman, who argued that serving one;s husband was the biggest dharma and brahmins should not become angry easily. She advised him to go to Mithila and learn from Dharmavyadha. He did that and then went back to serve his parents as per Mahabharata Vanaparva Chapters 206-216.

Kaushika finally attained naraka despite this. This was because, once, while he was meditating in a forest, a few robbers passed that way with loot. They were being chased by the rightful owners of the loot. It was Kaushika who told them the direction the robbers had gone in. So he was sent to naraka as per Mahabharata Karnaparva Chapter 96.
