Hope it isn't considered offtopic here; I don't know of any better places to ask.

It's from a wonderful film by Jim Jarmusch, The Limits of Control. This character is frequently seen to practice something that might be yoga (or maybe not?) and in the end of his sessions he places his hands in this configuration and bows slightly.

I want to read about the precise significance/context behind the gesture, but first I need to know its name.

I've searched among various yoga mudras for a little while and I couldn't identify any exact matches so far (at least a couple of details differ from what I see). ChatGPT couldn't do it either. At the same time it seems to me that it isn't the first time I see it.
