Yes, as poet Gary Snyder once wrote, truck drivers do get up earlier than zen students.
Monk chants lamentation of Jeremiah after, in visitors chapel, woman with white hat wills against two others who engage in dharma combat with her whether to keep overhead light on. White hat wins. Light stays on. Two, vanquished, step out to cross to other dark side chapel.
I have it easy. I can close my eyes.
Afterwards, side chapel empties, white hat shuts light and steps into dawn where later, after zazen, a single bird alights on bare branch overhead as I stand still in its presence.
Or, what's a retreat for?
