Kashi

He was so strong and bold and tough and always RIGHT in all his debates, that the opposing scholars were always afraid to face him. So it happened that one day he was invited at Kashi for a debate . He accepted the invitation - I'm ready, i'll come.

1. Half an hour later, one of them came and told him that he should not refer to Srimad Bhagavatam in his debate. He said - Ok, I'm ready. 
2. Then again after half an hour they said - you cannot refer to Ramayan and Mahabharat too. He said - Yes, I'm ready. 
3. Then again after half an hour they said - You also cannot refer to any of the Vedas. You have to refer to the Vedanta Sutra only. He said - Yes, I'm ready. 

Hearing this, they came and cancelled the debate !!
