— Xishan (1520-1604)
The Dharma is One Thing; humans are common people. In the Dharma there are two meanings: permanent meaning which cannot be changed, and transient meaning which is affected by the law of causation. In human beings, there are two temperaments: that of sudden awakening and that of gradual cultivation. Thus, it cannot be said that there are not means of teaching with letters and words. For instance, there is a saying: "In public there is not enough space for a needle, but in private a cart can pass."
