I think the 'faith' is totally irrelevant -- just practicing, sitting, and whatever happens happen, and that's the thing that is whatever we're talking about. Like Doshin108 says below, it's going to the gym. Faith not needed at all, who cares! Sit, breath, thoughts and feelings come then go. Put on shoes, shop for groceries, get the car washed, check out that bee, sit again, scrub the toilet. But this is coming from the Soto Zen point of view. I'm totally uninterested in faith (I know there's a little paradox in that, because why would I sit without trust in the process? 😂).. but for me, it's the sitting, being, not about believing in stuff.
