So now I'm like knee deep in Xingqiu's lore and trying to Think.

Because he got it thanks to like, revitalizing the martial principle of the Guhua Clan, but his joining the Guhua Clan was initially an extension of his gallivanting because he wanted to do martial arts and learning all of their little tricks to aid in his chivalrous pursuits.

I'm just thinking that like. Maybe he'd channel his ambitions into becoming a more serious martial artist, but I think that can ultimately be separated from his pursuits of justice.

He can grow out of his chivalry "phase", but his passion for the art he's studied and the principles he's founded can still remain. […] [His] ideas and pursuits of justice don't actually weigh in to him getting his vision to such a large extent.

I guess so?

I'm just looking at his vision story, and it's about these verses he wrote, and they were translated as such:

Guhua's arts I have studied long, in its secrets I am trained, now its long-lost depths fall upon me like the coming of blessed rain.

The beating heart of Guhua's sword art is as a shower of floating flowers. One amidst may seize a bloom, but those without read only doom.

The Guhua lance is a lantern's dance, like flames in night's deep glooming. Like sparks, they scatter with ease in the dark, then join like the daybreak looming.

They say the sword is as your arm — I say its glint is the beholder's eye, a light like the bright dawn coming.

Those who wander are burdened not. Freely they cut rain, and enlightened they pierce light. Like a snaking dragon, they cannot be subdued. In their right eye the blade, and in the other the spear.

And from what I can tell both from these and from the story itself, he received his vision from grasping the true meaning of the art, which is described in this paragraph:

The Guhua weapon arts stress using the weapon as an extension of your body, and indeed this is a common idea amongst the various schools of martial arts in Liyue. But the way Xingqiu saw it, the basis of the polearm and sword was the use of a Vision. Martial artists were meant to see a Vision as an extension of themselves, and see their weapon as an extension of the Vision. Hence, he says: the arts of both the polearm and the sword are just the art of the "eye."

And all of this is very much just focused on the art itself and not Xingqiu's own ideals. Maybe they helped him come to this conclusion, but that's not what it's all about.

So I have to wonder if like, Xingqiu's understanding of the Guhua arts as being the art of the "eye" thanks to performing it with a vision comes from some sort of understanding or belief on his part that vision holders have an advantage over ordinary people. And if it was a belief he held, I would certainly imagine it coming from the world he was raised in, in which one always has to assess the advantages or disadvantages that one might have in relation to other people, because he came from the world of business.

And if those founding principles of the Guhua Art are meant to be the thing that gave him his vision (which to be completely fair they might not be, if we want to assume he got his vision and then had this epiphany) then knowing what we know about Focalors and her belief that she (as the Hydro Archon, the one who holds the most power over that element) is the arbiter of what is right and just in her courtroom, those with a similar mindset in who has the right to be the arbiter of justice for others might receive a hydro vision.

This would also be different from Cyno, because Cyno's principles are rooted in his ideas about justice itself (from what I understand about him from the game because I am too braindead to actually read every single one of his character stories right now) rather than who has the right to carry out judgement. Because he gets his vision the night before becoming General Mahamatra, and he contemplates it for a while and comes to this conclusion:

"He was about to be entrusted with the sacred power to judge those who had erred, and this Vision would ensure that this sacred privilege could be exercised as intended."

Cyno understood his promotion as receiving the right to judgement, implying it was not something that he had before (not on the level that he was given by becoming General Mahamatra). Whereas someone like Focalors and her vision holders like Xingqiu (and I would argue Yelan and Ayato as well) claim that right for themselves.
