What if there were really, truly dropped away all thought of subject and object, all that is perceived by the senses, the sensing and the senses themselves …

What would “be” then (if we drop away even the word “be“) ??

There is a reality even prior to heaven and earth;
Indeed, it has no form, much less a name;
Eyes fail to see it; It has no voice for ears to detect;
To call it Mind or Buddha violates its nature,
For it then becomes like a visionary flower in the air;
It is not Mind, nor Buddha;
Absolutely quiet, and yet illuminating in a mysterious way,
It allows itself to be perceived only by the clear-eyed.
It is Dharma truly beyond form and sound;
It is Tao having nothing to do with words.

“Sweep away thoughts!” means one must do zazen. Once thoughts are quieted, the Original Face appears. Thoughts can be compared to clouds. When clouds vanish, the moon appears. The moon of suchness is the Original Face. Thoughts are also like the fogging of a mirror. When you wipe away all condensation, a mirror reflects clearly. Quiet your thoughts and behold your Original Face before you were born!
