They seem to be souls which enter the object during its manufacture, like the human soul enters a baby in stages during gestation, being mostly fully housed by the end of the first trimester.
Sometimes they seem able to see ahead, and will call to you - I got a thing to randomly search for a specific type of ring on eBay, and one called to me that I could not get out of my mind, for days, but then later it proved important to a specific major working.
I had no, as in zero, previous knowledge about that type of gemstone beforehand, and no idea it would become linked to this work, which I did not foresee!
However just as your organs have spirits of their own, so the gemstones, metals, paper, or other materials used also have simpler souls of their own, and this is why blessing the makings, before creating a talisman or other tool, is useful.
Pro-tip: send out a call for the spirits of powerful objects which have been lost or buried long ago, when making your own tools, to have access to the tools of past masters of the art, and even to enter objects like phones before you buy them, so they don’t blow up on you when there’s a lot of spiritual energy going the rounds.
