I made a topic a long while ago when Inazuma was still fresh where I theorized that maybe Kusanali's title the Lesser Lord meant that while Sumeru adored their new Archon they didn't quite respect her as a real leader like they would have the God of Woods.
Here you can pretty much see that isn't the case with at least Nazafarin. But then again Nazafarin is a normal citizen. She wouldn't have a say in Sumeru's politics and it's likely even if the scholars of Academia don't respect Kusanali they would still show her the proper ceremony in public since they still love her. Either way though it's really cool to see this bow Nazafarin is doing. We've seen the more Christian style of Mondstadt towards Barbatos, Liyue's words of veneration for Morax and Inazuma's celebrity of Ei. It looks like Sumeru has a more Hindu/Buddhist bow. I'm not sure if Persians do the same thing because the searches just give me the Muslim prayer rug. 
The only other thing I've found is a Persian bow from men to women which is interesting because from the description it sounds like a really standard animation in Genshin.
But speaking of Muslim prayer rugs there was this line from Nazafarin.
Neither eating nor drinking. That is what we call fasting. And of course many religions have this act. Actually I think Judaism is probably the most extreme since it's like 26 hours of not eating or drinking during Yom Kippur. But this line immediately reminded me of Ramadan where everybody fasts like this during the day everyday for a whole month. And I think the idea is doing so can bring a person closer to God therefore having a revelation is probably part of the deal. Nazafarin realized to do this event after her fasting.
I actually bring up Islam here because there's another chapter to my whole Achaemenid Persia theory about Sumeru. A long while into Persia's history the Muslim world started to rise and there's a thing called the Muslim Conquests and they would conquer all of that version of Persia aka the Sassanid Empire. One of the points I made about why I thought Kusanali might be loved but not respected was because the Achaemenid Persians moved in and conquered the older empires of the area too namely Babylonia where our Seven Classical Planets come from. The Muslim Conquests was actually my starting point with that theory so if that's being referenced here maybe that was also the path MiHoYo took to research for how they wanted Sumeru to go.
It's pretty cool that a game's taking us on a walk through world history haha.
