You arrive, and take your shoes off
Shoes come off at the door of the hall, and there will be a rack or a heap of them to tell you where. Inside, people sit on cushions on the floor facing a raised seat, the throne, which stays empty until the teacher comes in. There are usually chairs at the back for anybody whose knees need them, and using one is not a failure.
Find a cushion, sit down, and wait. Nobody will brief you. This is the part that unsettles newcomers most, and it is not coldness: it is that everybody around you has done it a hundred times and has stopped noticing that it needs explaining.
In practicePhone off, not silent. Feet not pointing at the throne or at the shrine.
