Do not go by oral tradition, by lineage of teaching, by hearsay, by a collection of texts, by logic, by inferential reasoning, by reasoned cogitation, by the acceptance of a view after pondering it, by the seeming competence of a speaker, or because you think, ‘The ascetic is our teacher.’ But when you know for yourselves, ‘These things are unwholesome; these things are blamable; these things are censured by the wise; these things, if undertaken and practiced, lead to harm and suffering,' then you should abandon them.
