Genjō Kōan: Actualizing the Fundamental Point
Eihei Dōgen

1. As all things are buddha dharma, there are delusion, realization, practice, birth [life] and death, buddhas and sentient beings. As myriad things are without an abiding self, there is no delusion, no realization, no buddha, no sentient being, no birth and death. The buddha way, in essence, is leaping clear of abundance and lack; thus there are birth and death, delusion and realization, sentient beings and buddhas. Yet in attachment blossoms fall, and in aversion weeds spread.
2. To carry the self forward and illuminate myriad things is delusion. That myriad things come forth and illuminate the self is awakening.
Those who have great realization of delusion are buddhas; those who are greatly deluded about realization are sentient beings. Further, there are those who continue realizing beyond realization and those who are in delusion throughout delusion. When buddhas are truly buddhas, they do not necessarily notice that they are buddhas. However, they are actualized buddhas who go on actualizing buddha.
3. When you see forms or hear sounds, fully engaging body-and-mind, you intuit dharma intimately. Unlike things and their reflections in the mirror, and unlike the moon and its reflection in the water, when one side is illumined, the other side is dark.
4. To study the way of enlightenment is to study the self. To study the self is to forget the self. To forget the self is to be actualized by myriad things. When actualized by myriad things, your body and mind as well as the bodies and minds of others drop away. No trace of enlightenment remains, and this no-trace continues endlessly.
