As above down to:

“What now, friend, is the cause and reason why this has not been declared by the Blessed One?”

“Friend, it is one who is not devoid of lust for form, who is not devoid of desire, affection, thirst, passion, and craving for form, that thinks: ‘The Tathagata exists after death,’ or ‘The Tathagata does not exist after death,’ or ‘The Tathagata both exists and does not exist after death,’ or ‘The Tathagata neither exists nor does not exist after death.’ It is one who is not devoid of lust for feeling … who is not devoid of lust for perception … who is not devoid of lust for volitional formations … who is not devoid of lust for consciousness, who is not devoid of desire, affection, thirst, passion, and craving for consciousness, that thinks: ‘The Tathagata exists after death’ … or ‘The Tathagata neither exists nor does not exist after death.’

“But, friend, one who is devoid of lust for form … who is devoid of lust for feeling … who is devoid of lust for perception … who is devoid of lust for volitional formations … who is devoid of lust for consciousness, who is devoid of desire, affection, thirst, passion, and craving for consciousness, does not think: ‘The Tathagata exists after death’ … or ‘The Tathagata neither exists nor does not exist after death.’

“This, friend, is the cause and reason why this has not been declared by the Blessed One.”
