Studying the Buddha way is studying oneself. Studying oneself is forgetting oneself. Forgetting oneself is being enlightened by all things. Being enlightened by all things is to shed the body-mind of oneself, and those of others. No trace of enlightenment remains, and this traceless enlightenment continues endlessly.
DogenUnderstand clearly that when a great need appears a great use appears also; when there is small need there is small use; it is obvious, then, that full use is made of all things at all times according to the necessity thereof.
DogenIn 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.
