Down, up. No receipt.
A small cue can be a hinge: a breath before tea, a bow before walking, a pause before speaking. It is not a test of virtue. It is a place where attention lands.
The trouble starts when the cue becomes a costume. We begin to check the glow, the polish, the evidence that we are kind. Then the hinge turns inward, and the room narrows.
In zazen, the body sits, and the sitting sits. In shikantaza, just sitting, there is no extra proof to add. A kitchen bow can do the same: turn toward the cup, the person, the next act, then let go of the turning.
I am curious how people keep a cue alive without making it a ruler. Does it stay small? Does it point outward? Does it dissolve into ordinary work?
What does your practice do when the cue is working, and when it is only performing?
