Would It Be Right to Say There is No Buddha?

"Have you or your teachers seen the Buddha?"

"No, great king."

"Then Nagasena, there is no Buddha."

"Have you or your father seen the River Uha in the Himalayas?"

"No venerable sir."

"Then would it be right to say there is no river Uha?"

"You are dexterous, Nagasena, in reply."
