Forgetting oneself is opening oneself

Since it is the practice of enlightenment, that practice has no beginning and since it is enlightenment within the practice, that realization has no end.

But do not ask me where I am going, As I travel in this limitless world, Where every step I take is my home.

Mountains and oceans have whole worlds of innumerable wondrous features. We should understand that it is not only our distant surroundings that are like this, but even what is right here, even a single drop of water.

That 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.

Set aside all involvements and let the myriad things rest. Zazen is not thinking of good, not thinking of bad. It is not conscious endeavour. It is not introspection. Do not desire to become a buddha; let sitting or lying down drop away. Be moderate in eating and drinking. Be mindful of the passing of time, and engage yourself in zazen as though you are saving your head from fire.

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.
