I'm into these circles and I think there's a fair bit of concern trolling. People see red as soon as these type of people mention Tarot or egregores which is understandable but I think off the mark.
Truth is that pretty much all of them are simply Christian Neo-Platonists like most of the medievals were, they're trying to articulate it for the modern world and trying to incorporate the same worldview as most medievals.
If you dig into it you'll find that a guy like Roger Buck or Peter K. hates sorcery as much as the next guy, they're just trying to have the same vision you'll find in Honorius' De Imago Mundi or Vincent's Speculum Naturale.
"Every creature in the world is, for us, like a book and a picture and a mirror.
(Omnis mundi creatura / Quasi liber et pictura / Nobis est et speculum)"
-Alain de Lille
"The whole sensible world is like a kind of book written by the finger of God. and each particular creature is a symbol, not arbitrarily invented by human decision, but instituted by the divine will to manifest the invisible things of God's wisdom."
-Hugh of St. Victor
It's the same worldview that confidently says in a bestiary:
"The lion erasing its tracks with its tail signifies the way Jesus concealed his divinity, only revealing himself to his followers. The lion sleeping with its eyes open signifies Jesus, physically dead after crucifixion, but still spiritually alive in his divine nature. The lion roaring over his dead cubs to bring them to life represents how God the father woke Jesus after three days in his tomb."
