In plain words
Then they said to the ear, "Sing the Udgītha for us." "So be it," said the ear, and sang the Udgītha for them. Whatever enjoyment there is in the ear, that it sang for the gods; but the hearing of what is fair it kept for itself. The demons knew, "By this singer they will overcome us." They rushed upon it and pierced it with evil. That evil is the hearing of what is unseemly; that is the evil.
