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.
DogenRealization doesn't destroy the individual any more than the reflection of the moon breaks a drop of water. A drop of water can reflect the whole sky.
DogenStudying 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.
DogenThrough one word, or seven words, or three times five, even if you investigate thoroughly myriad forms, nothing can be depended upon. Night advances, the moon glows and falls into the ocean. The black dragon jewel you have been searching for, is everywhere.
