In 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.
DogenTo start from the self and try to understand all things is delusion. To let the self be awakened by all things is enlightenment.
