佛說處處經 1.29

1.29

佛言：「舍利弗！有三語，悉以知人意：一者、麁語；二者、深語；三者、牽語。得是三語，有善意即見，有惡意亦見，有忍意亦見，欲意從是三語悉知人意。」

The Buddha said: "Śāriputra! There are three kinds of speech by which the minds of people can be entirely known: the first is coarse speech; the second is deep speech; the third is drawing speech. When these three kinds of speech are attained, if there is a wholesome intention, it is immediately seen; if there is an unwholesome intention, it is also seen; if there is an intention of forbearance, it is also seen; all of a person's thoughts and intentions are known through these three kinds of speech."
