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.
DogenIf he cannot stop the mind that seeks after fame and profit, he will spend his life without finding peace.
DogenThat the self advances and confirms the ten thousand things is called delusion; that the ten thousand things advance and confirm the self is called enlightenment.
DogenSet aside all involvements and let the myriad things rest. Zazen is not thinking of good, not thinking of bad. It is not conscious endeavour. It is not introspection. Do not desire to become a buddha; let sitting or lying down drop away. Be moderate in eating and drinking. Be mindful of the passing of time, and engage yourself in zazen as though you are saving your head from fire.
