Most books about spirits either treat them as psychological metaphors or as vending machines.
Consorting with Spirits is instead about relationship, the long, ordinary, maintained kind. Miller argues that the gods, ancestors, land spirits, familiars, and dead you work with are actual others with their own interests, and that the quality of what you get from them tracks the quality of what you build with them over years. That premise sounds obvious until you notice how few practical books are structured around it.
Miller covers how to identify who's already around you, how to make contact, what offerings actually accomplish and why consistency beats extravagance, how to discern real communication from your own noise, and how to handle it when a relationship sours or a spirit turns out not to be what it claimed. There's clear-eyed material on protection and on the difference between a spirit you invite in and one you merely tolerate.
Miller writes from decades of practice across Western ceremonial, Tantric, and folk streams, and he's blunt about what he doesn't know. The tone is workmanlike, with no mystique, no gatekeeping, and plenty of "here is what I do and here is where it went wrong."
Strong for solitary practitioners who feel like their practice has gone flat, and for anyone whose devotional work has outgrown correspondence tables and needs an actual method.
