The one and only thing required is to free oneself from the bondage of mind and body alike, putting the Buddha's own seal upon yourself. If you do this as you sit in ecstatic meditation, the whole universe itself scattered through the infinity of space turns into enlightenment. This is what I mean by the Buddha's seal.
DogenThat the self advances and confirms the ten thousand things is called delusion; that the ten thousand things advance and confirm the self is called enlightenment.
DogenBe moderate in eating and drinking. Mindful of the passing of time, engage yourself in zazen as though saving your head from fire.
DogenBut do not ask me where I am going, As I travel in this limitless world, Where every step I take is my home.
