In zazen, bowing can be plain: a nod to the cushion, to the room, to the fact that we are here. But sometimes bowing starts to mean arrival, as if the body has settled into some final place. If the bow becomes a receipt for effort, the body may be still while the mind is already grading the sit.
In shikantaza, just sitting, the movement is not a ticket. It is a turning. The hands settle, the spine straightens, the breath is not chased. A sesshin can make this very vivid: after many sits, the same gesture can feel like a small gate. That is useful. It can also become a test: Did I bow enough? Is the posture now correct enough?
I am curious how others keep reverence alive without letting it harden into a score. Can a bow stay a bow when it starts to mean arrival? Or does the gate itself need to be set down?
