Not long after the Buddha departed, some other wanderers said to the wanderer [Poṭṭhapāda], “Why were you listening to the teaching of that ascetic Gautama and approving of what he said? Gautama says, ‘“Self and the world is permanent … the Tathāgata neither dies nor doesn’t die” are incompatible with meaning … so I don’t explain them.’ Why did you approve of those words? We cannot have such discussions with the ascetic Gautama.”
