‘Students of the Way, you must not cling to your own personal views. Even though you may understand, you should search widely for a good teacher and examine the sayings of the old Masters if you feel there is something lacking or that there is some understanding superior to your own. Yet you must not cling to the words of the old sages either; they too, may not be right. Even if you believe them, you should be alert so that, in the event that something superior comes along, you may follow that.’ (Shobogenzo Zuimonki)
The key word here, as usual, is ‘cling.’
