If you wish
to bring the two matters
of birth and death to conclusion,
and pass directly beyond the triple-world,
you must penetrate the koan “This
very mind is Buddha.”
Tell me:
What is its principle?
How is it that this very mind
is Buddha? And “this very
mind” — just what is
it like?
Investigate it coming. Investigate it going.
Investigate it thoroughly and exhaustively.
All you have to do is keep this koan
constantly in your thoughts.
