Since 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.
DogenThere are mountains hidden in mountains. There are mountains hidden in hiddenness. This is complete understanding.
