In Jane Hirshfield's "Women in Praise of the Sacred," the author explains that Kojiju (a buddhist nun from the 12th century) poetry reflects the Buddhist teaching that enlightenment is innate: not something to be looked for outside ourselves, but always already present, waiting to be seen at any moment.


"Merely to know
the Flawless Moon dwells pure
in the human heart
is to find the Darkness of the night
vanished under the clearing skies."

Kojiju



And in Tao Te Ching Chapter 47, translated by Ursula K. Le Guin, we can read:

"You don't have to go out the door
to know what goes on in the world.
You don't have to look out the window
to see the way of Heaven.
The farther you go
the less you know.

So the wise soul
doesn't go, but knows;
doesn't look, but sees;
doesn't do, but gets it done."
