‘Students cannot gain enlightenment simply because they retain their preconceptions. Without knowing who taught them these things, they consider the mind to be thought and perceptions, and do not believe it when they are told that the mind is plants and trees. They think of the Buddha as having marvelous distinguishing marks, with radiance shining from his body, and are shocked when they are told he is tile and pebble. Such preconceptions were not taught to them by their parents, but students come to believe them for no other reason than that they have heard about them from others over a long period of time. Therefore, when the Buddhas and the Patriarchs categorically state that the mind is plants and trees, revise your preconceptions and understand plants and trees as mind. If the Buddha is said to be tile and pebble, consider tile and pebble as the Buddha. If you change your basic preconceptions, you will be able to gain the Way.’ (Shobogenzo Zuimonki)
