I set the cushions a little apart before a sit, so we can see each other without crowding. A small bell can do that too: it marks the edge of a question, not the answer.
When a group talks about the teachings, I sometimes notice a knowing that has turned into a possession. It wants to be displayed. The shoulders lift. The breath shortens. Then the question gets quieter.
I would be glad to hear how others keep understanding humble. From study, does a plain question in the text help? From sitting, does returning to the body do it? From ritual, does bowing keep the heart open? From community, does listening to a less experienced friend change the room?
My own small practice is to ask, “What am I trying to prove?” and then let the breath answer. Not with a score. Just with a softer turn.
What plain practice keeps a question alive without making it a certificate?
