The Buddha was an absolute master in debate.
People from all over India would come to the Buddha to ask him questions and sometimes, to try to defeat him in debate. And it’s a great to see how the Buddha actually handled himself against these people – because sometimes, he would come up with the coolest answers!
The Story of Akkosa
In the Akkosa Sutta, a man named Akkosa found out that one of his clansmen had just become a disciple of the Buddha. Outraged, Akkosa went to the Buddha to give the Buddha a piece of his mind – he hurled abuse and insults at the Buddha, telling the Buddha what he thought of him in no uncertain terms.
The Buddha was unmoved in the slightest by this barrage of insults and just asked a question in return:
“Do you sometimes receive visitors as guests?”
“Yes I do” replied Akkosa.
“And when they come, do you offer them food and drink and courtesies?” asked the Buddha.
“Yes, sometimes I do” Akkosa said.
“So what if your guests don’t accept what you offer to them – where do the food, drink and courtesies return to?”
“They return to me of course!” Akkosa answered.
“Akkosa, you came here today, hurling insults and abuse at me. I do not accept what you have offered. So where do these insults and abuse return?”
Akkosa got the picture.
Isn’t that so funny! Akkosa was even won over by how calm the Buddha was in the face of insult – how the Buddha didn’t retaliate with anger against his angry attacks. Akkosa was also won over by wisdom.
