I'm not actually sure we know enough about imperial methods to make this claim. Imperial geomancy, for example, requires an extraordinary amount of understanding. So it feels like you are treating 'imperial' as a synonym for 'bad' rather than a philosophy of it's own, with the comprehensive rejection of the idea.
'More imperial' is just a vector. Kinda in the same way that being in Arizona rather than California is being more eastern, even though both are western states. In this case, 'more imperial' is just about coming closer to imposing an artificial environment over the natural (spiritual) environment rather than changing yourself to better survive it. It's not a moral judgement, it's just meant to be descriptive.
But since being aware of, and honest about, the meaning of the choices we make has a strong influence on how smoothly future choices go, it seems worth getting people on the same page here.
Weilu methods are about living within spirits and nature. Imperial methods are about living outside of nature and spirits because man is not barbaric.
For the Weilu methods, you have to understand the spirits to really work with them. It's mostly built on pacts and personal bonds and is thus difficult to scale up. For the imperial methods to work, you don't try to understand the spirit.
I understand and agree that they're different philosophies. But somehow, someway, "imperial"got brought into this saltfest as a way to make one method look worse than the other, when it wasn't brought up in any of the arguments iirc, so here we are.
I agree that imperial geomancy requires an incredible amount of understanding of geomantic principles, but not of spirits, their natures, and their effects on the land. Like Wang Lian said, humans are the inheritors of the Earth and shaping it is their birthright. They have a deep understanding of shaping it, regardless of what had been there before. Weilu methods are about living in harmony with the world as it is, which includes spirits and nature. It also requires understanding of nature and spirits. They're different fields and philosophies and this have different understandings.
Grounding is still trying to understand spirits. It's just taking a forest view (using an understanding of a spirit' environment to understand its nature and this nullify their passive environmental effects) compared to Dispersion, and that's okay, imo.
There is no less interaction. If anything, this may make MoSS appear even more on the narrative for training our version of the ministry.
Ling Qi hesitated before saying priestess, because while similar to what she does (communicate with wild spirits) it is not the same. The spirits on her land are not just hazards to be appeased with a yearly ceremony or culled for parts. They are also potential teachers, friends, siblings and even lovers, if her people follow her path. Which is not the ministry approved imperial way.
Ling Qi does not like taking leadership roles a lot, even though she's very good at them. This is still a Weilu method. That's why Jiao said he feels sorry for the people we'll drag along with us to go spiritseeking. It's why he believes that the Ministry of Spiritual Affairs won't like us.
This won't suddenly stop Ling Qi from believing that spirits are family.
Need I remind you that Xin is the one recommending the two paths that weirdo Weilus who use this old art normally take with its development?
