Yes, exactly. But I was trying to trace the notion, popularized by Findhorn and New Agers, that fairy-like creatures were "assigned" to each type of plant to make it grow: the pine tree deva, the tomato deva, et al. I was wondering if this was part of traditional belief (i.e., cunning folk and the like), or whether it was something the more elite occultists (John Dee and his ilk) subscribed to. This passage seems to imply that it is a Neo-Platonic notion, which means it was probably something the elites subscribed to. Which doesn't mean that it wasn't also held by the more traditional practitioners—there just doesn't seem to be much documentation for it.
