Manual of Zen Buddhism

With nothing wanting, nothing superfluous:
It is indeed due to making choice
That its suchness is lost sight of.

4. Pursue not the outer entanglements,
Dwell not in the inner void;
Be serene in the oneness of things,
And [dualism] vanishes by itself.

5. When you strive to gain quiescence by stopping motion,
The quiescence thus gained is ever in motion;
As long as you tarry in the dualism,
How can you realize oneness?

6. And when oneness is not thoroughly understood,
In two ways loss is sustained:
The denying of reality is the asserting of it,
And the asserting of emptiness is the denying of it.[2]

7. Wordiness and intellection—
The more with them the further astray we go;
Away therefore with wordiness and intellection,
And there is no place where we cannot pass freely.

8. When we return to the root, we gain the meaning;
When we pursue external objects, we lose the reason.
The moment we are enlightened within,
We go beyond the voidness of a world confronting us.

9. Transformations going on in an empty world which confronts us
Appear real all because of Ignorance:
Try not to seek after the true,
Only cease to cherish opinions.

10. Abide not with dualism,
Carefully avoid pursuing it;
As soon as you have right and wrong,
Confusion ensues, and Mind[3] is lost.

11. The two exist because of the One,
But hold not even to this One;
When a mind is not disturbed,
The ten thousand things offer no offence.

12. No offence offered, and no ten thousand things;
No disturbance going, and no mind set up to work:
The subject is quieted when the object ceases,
The object ceases when the subject is quieted.

13. The object is an object for the subject,
The subject is a subject for the object:
Know that the relativity of the two
Rests ultimately on one Emptiness.

14. In one Emptiness the two are not distinguished,
And each contains in itself all the ten thousand things;
When no discrimination is made between this and that.
How can a one-sided and prejudiced view arise?

15. The Great Way is calm and large-hearted,
For it nothing is easy, nothing is hard;
Small views are irresolute,
The more in haste the tardier they go.

16. Clinging is never kept within bounds,
It is sure to go the wrong way;
Quit it, and things follow their own courses,
While the Essence neither departs nor abides.

17. Obey the nature of things, and you are in concord with the Way,
Calm and easy and free from annoyance;
But when your thoughts are tied, you turn away from the truth,
They grow heavier and duller and are not at all sound.

18. When they are not sound, the spirit is troubled;
What is the use of being partial and one-sided then?
If you want to walk the course of the One Vehicle,
Be not prejudiced against the six sense-objects.

19. When you are not prejudiced against the six sense-objects,
You are then one with the Enlightenment;
The wise are non-active,
While the ignorant bind themselves up;
