A Dog Was Beaten. He Asked Rama to Punish the Man With a Promotion.

Description

In Ayodhya, a dog with a wounded head waits at the gate and will not come in without the king's permission. The man who beat him confesses, the sages rule that he cannot be put to death, and the dog asks for a strange sentence: make him kulapati, the head of the temple at Kalanjara.

A promotion.
Only the dog knows why that is a punishment.
