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.
DogenContinuous practice, day after day, is the most appropriate way of expressing gratitude. This means that you practice continuously, without wasting a single day of your life, without using it for your own sake. Why is it so? Your life is a fortunate outcome of the continuous practice of the past. You should express your gratitude immediately.
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.
