Here’s the webinar from this morning (click here), working with the section of Dogen’s Instructions for the Cook that includes this poem by Xuedou that was great nourishment for me when I was tenzo at Hokyoji many years ago: 

One, seven, three, five
The truth you search for cannot be grasped.
As night advances, a bright moon, 
illuminates the whole ocean.
The black dragon’s jewel is found in every wave.
Looking for the moon, it is here, 
in this wave, in the next.
