The Mirror of Zen

Commentary

Teachings such as this do not neccessarily apply to wise people
of superior capacity, who are not bound by such limitations, but
rather to practitioners of middling or inferior capacity, who
cannot advance easily to such higher stages.
So, in sutra teachings one can distinguish between things
that never change and things that chang according to causes
and conditions. Most people think that there is also a conceptual
order between sudden enlightenment and gradual practice,
suggesting that one follows after the other. In the Zen dharma,
however, when you keep moment-mind, abiding at one point,
things that never change and things that change according to
causes and conditions, true nature and appearances, and substance
and function are all realized as existing simultaneously. It
is therefore extremely important that you abandon the view that
things do or do not exist: everything is fundamentally the same
True Suchness, as it is, and yet everything is clearly distinct.
For this reason, all the eminent teachers of the Zen school
taught the dharma while abandoning attachment to words. They
pointed directly to moment-mind, which is before thinking arises:
"attain your true nature and become Buddha." "This way is the
true abandonment of the scriptural teaching.
