"Once a monastic asked the Tang Dynasty Chinese National Teacher, Nanyang, 'Do the insentient understand the expressing of the Way?' The National Teacher said, 'They express the Way continually, energetically, ceaselessly.' The monastic said, 'Why can't I hear it?' The National Teacher replied, 'The fact that you don't hear it has nothing to do with others hearing it.' The monastic said, 'I don't understand. What kind of person can hear it?' The National Teacher said, 'All the holy ones can hear it.' The monastic asked, 'Do you hear it?' The National Teacher said, 'I do not hear it.' The monastic said, 'If you do not hear it, how do you know that the insentient can express the Way?' The National Teacher said, 'Fortunately I do not hear it. If I did, I would be one of the holy ones and you would not be able to hear me expressing the Way.' The monastic said, 'In that case, sentient beings can't hear it.' The National Teacher said, 'I express the Way for the sake of sentient beings, not for the sake of the holy ones.' The monastic said, 'Then what happens when sentient beings do hear you?' The National Teacher said, 'At that moment they are not sentient beings.'"
