Life and death are nothing but the mind. Years, months, days, and hours are nothing but the mind. Dreams, illusions, and mirages are nothing but the mind. The bubbles of water and the flames of fire are nothing but the mind. The flowers of the spring and the moon of the autumn are nothing but the mind. Confusions and dangers are nothing but the mind.
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.
