Ponder the fact that someone realized the Way by hearing the sound of bamboo; that another clarified the Mind at the sight of peach blossoms. How could it be possible to differentiate smart bamboo trees from dull ones, or deluded ones from enlightened ones? How could there be shallow or deep, wise or stupid among flowers? The flowers bloom every year yet not everyone attains enlightenment by viewing them. Stones often strike bamboo yet not everyone who hears the sound clarifies the Way. Only through the virtue of long study and continuous practice, with the assistance of diligent effort in the Way, does one realize the Way or clarify the Mind. This did not occur because the sound of the bamboo was especially wonderful, nor because the color of the peach blossoms was particularly profound. Although the sound of bamboo is marvelous, it does not sound of itself; it cries out with the help of a piece of tile. Although the color of peach blossoms is beautiful, they do not bloom of themselves; they open with the help of the spring breeze. - Shobogenzo Zuimonki, Book 4, Chapter 5.
