A small ritual can be useful when it does something specific: it turns attention toward the being or teaching before the sitting begins. In the early texts, the Buddha often describes going to the presence of the teacher, paying respect, and listening with care. For example, the Dhamma is compared to a raft, and the path includes right effort and right mindfulness, not a set of automatic phrases. A bow, a pause, a remembered image of the Buddha can act like a hinge. If it opens the mind to others, it is doing its work. If it becomes a performance, a mark of status, or a way to avoid contact, it has missed the point.
I am curious how people with different views handle this. Does a small ritual help you settle, or does it seem like adding weight? What part of a sitting, if any, seems to need a cue, and what does that cue do in practice?
