Zazen is an activity that is an extension of the universe. Zazen is not the life of an individual, it's the universe that's breathing.
DogenWhy abandon a seat in your own home to wander in vain through dusty regions of another land? If you make one false step, you miss what is right before your eyes.
DogenThough it has no thought of keeping watch, it's not for naught that the scarecrow stands in the grain field.
DogenIn doing zazen it is desirable to have a quiet room. You should be temperate in eating and drinking, forsaking all delusive relationships. Setting everything aside, think of neither good nor evil, right nor wrong. Thus having stopped the various functions of your mind, five up even the idea of becoming a Buddha.
DogenLife 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.
