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.
DogenSince we are provided with both a body and a mind, we grasp onto the physical forms we see. Since we are provided with both a body and a mind, we cling to the sounds we hear. As a consequence, we make ourselves inseparable from all things, yet we are not like some shadowy figure 'lodging' in a mirror or like the moon in water. Whenever we witness what is on the one side, its opposite side will be in darkness.
