Texts : Hyle und Coayle, Hermetic Recreations, Mutus Liber, Canseliet's/Fulcanelli, Arcana Divina, Chemical Moonshine, Donum Dei, ICH for example. Rain, dew, etc enters this category too, but at the frontier with the ersatz paths, because of the lack of spirit in these Paths.
Texts : Flamel, Cosmopolite, Trevisan, Zachaire, Jehan de Meung, Bacstrom's blood way, and everything related to metals only (cinnabar, antimony paths, amalgams, and so on) ...
The Pure create it's own magnet, and then the spirit flow down, and in the Bastard, we create the magnet for the Spirit. So we imitate the process. And the Ersatz is just imitating the whole process, with material magnet, material spirit. just a pale copy.
I make a clear distinction between Spiritus Mundi, which is for me a condensed matter from "no where" (apparently) and the "Heaven/second hand", which are already in the matter, and that is just spagerically revealed. Even if the Second hand comes from SM, which is the case for everything in this universe.
The Spirit is everywhere, but IMO, there is a difference nonetheless.
