In the assemblies of the enlightened ones there have been many cases of mastering the Way bringing forth the heart of plants and trees; this is what awakening the mind for enlightenment is like. The fifth patriarch of Zen was once a pine-planting wayfarer; Rinzai worked on planting cedars and pines on Mount Obaku. . . . Working with plants, trees, fences and walls, if they practice sincerely they will attain enlightenment.
Not thinking about anything is zen. Once you know this, walking, standing, sitting, or lying down, everything you do is zen. To know that the mind is empty is to see the buddha. . . . Using the mind to reality is delusion. Not using the mind to look for reality is awareness. Freeing oneself from words is liberation.
Although profoundly "inconsequential," the Zen experience has consequences in the sense that it may be applied in any direction, to any conceivable human activity, and that wherever it is so applied it lends an unmistakable quality to the work.
