The one true thing

The Cloud by Dogen
This slowly drifting cloud is pitiful;
what dreamwalkers men become.
Awakened, I hear the one true thing—
Black rain of the roof of Fukakusa temple.

A couple weeks ago in my Tuesday evening meditation group someone mentioned he had been reading a suggested keeping in mind  the phrase, "Now.  Here.  This."

It's the theme of Dogen's poem and a theme I'm trying to remember as I listen for the one true thing in my life this evening. 

Now. 
             
               Here.
                 
                              This.
