There was a scholar of  named  Vidyasagar. He was well versed in all subjects. He had also travelled to many  parts of India and had defeated many scholars in the debates.

Once, he  came to Vijayanagar. At Vijayanagar, the king welcomed  him as his guest, with due respect.During his conversation with the king, Vidyasagar said, "I  have heard of the scholar Tenali Raman. I would like to debate with him. I will surrender all my titles to them if he defeat me."

Krishna Raya agreed to have the contest on the next day and sent  Vidyasagar to the guest house. Then, he called Raman and he was ready to meet the challange of Vidyasagar.

King made necessary arrangements for the contest. Next day, Raman along with the other great scholars entered the court. Raman was carrying a  big book covered with a cloth. As per schedule, the king signalled for the debate to begin. Raman invited Vidyasagar for a  debate on that book. When Vidyasagar asked the name of the book,  Tenalirama revealed its name as "Tilakmahishabandhana". The scholar from  kashi had never heard of this book. At the same time, he did not want to face  the defeat so soon. So, he told the king, "Sir, I remember to have  read this book long back. I need sometime for me to refresh." The king honoured his request. 

Vidyasagar and his disciples returned back to their camp.The name of the book, was indeed a riddle for him. He was certain that, he  will embrace the defeat on the next day. Hence, to avoid the disgrace in front  of others, he and his disciples ran away from Vijayanagar on the same night.
