[758] Then, on a later occasion, King Pasenadi of Kosala approached the Blessed One; having approached, he paid homage to the Blessed One and sat down to one side. Seated to one side, King Pasenadi of Kosala said this to the Blessed One: "How is it, venerable sir — does the Tathāgata exist after death?"
"That, great king, has not been declared (abyākata) by me: 'The Tathāgata exists after death.'"
"Then, venerable sir, does the Tathāgata not exist after death?"
"That too, great king, has not been declared by me: 'The Tathāgata does not exist after death.'"
"How is it then, venerable sir — does the Tathāgata both exist and not exist after death?"
"That, great king, has not been declared by me: 'The Tathāgata both exists and does not exist after death.'"
"Then, venerable sir, does the Tathāgata neither exist nor not exist after death?"
"That too, great king, has not been declared by me: 'The Tathāgata neither exists nor does not exist after death.'"
"When asked, venerable sir, 'How is it — does the Tathāgata exist after death?' you say, 'That, great king, has not been declared by me: "The Tathāgata exists after death."' … When asked, venerable sir, 'Then does the Tathāgata neither exist nor not exist after death?' you say, 'That too, great king, has not been declared by me: "The Tathāgata neither exists nor does not exist after death."' What now, venerable sir, is the cause, what is the reason, why this has not been declared by the Blessed One?"
