I know social media is not the place to get this kind of information, but I keep seeing people use “Grimoire” and “Book of Shadows” interchangeably.
Mine started as a “grimoire” when I was 16, scribbling correspondences and moon phases, but somewhere along the way it shifted into something I’d call a BOS without me even noticing.
Is the difference really just that a BOS carries that Wiccan lineage weight, while a grimoire is more of a working reference manual? When I flip through mine, I’ve got pressed herbs next to sigils next to journal entries about how a ritual actually FELT. Oh wait, hold on, my “grimoire” has dated entries and dreams in it too, which kind of blows my own theory apart.
The way I see it, a grimoire is basically just the spells extracted out. Like if you pulled only the spell content from your BOS and copied it separately, that’s your grimoire.
Your BOS is where the shadows live, the impressions and images from the ritual work. The ritual stuff is really the heart of it.
Give that framework a try and see if it helps sort out what you’ve got going on.
Both went in the same book for me. Color-coding your pages might scratch that organizational itch if you really want to keep them separate, but I stopped worrying about it ages ago and nothing bad happened.
Sometimes there’s just no difference worth stressing over.
The main difference comes down to lineage and transmission. A BOS gets passed down within a tradition, initiator to initiate, usually hand-copied. A grimoire is more of a standalone reference work. Think medieval European and Arabic magical texts.
What you’re describing sounds like it started as personal reference material and picked up more spiritual weight over time. That’s pretty common for practitioners.
Grimoire was traditionally just a magician’s spell book. A Book of Shadows specifically described what a Traditional Wiccan coven actually did in practice.
Both terms have stretched so much over the years that there’s tons of overlap now.
In traditional Wicca, the BOS is a framework you copy by hand from your initiator. Same for every Wiccan in that lineage.
Most witches online have personal books full of their own work, spells, rituals, whatever they want. That’s a different thing from the lineage framework you inherit. The Book of Spells has that specific inherited structure (passed down, copied verbatim). The spell book is yours to fill however you want. Neither one is wrong, just different traditions.
Book of Spells is basically your own personal mix of a journal and spell book.
A Grimoire is sometimes shared by a coven or lineage. You wouldn’t write things too personal in it but it would be spells and magickal findings you find important because it would pass to a descendant or someone you deemed worthy of carrying the craft.
The format itself might be telling you something. A grimoire was historically bound and finalized, while a BOS was meant to be living and added to until death, and then in some lineages burned.
So when you flip through yours and find dated dreams next to pressed herbs, it might feel finished or it might feel like it’s still breathing.
Labels stopped mattering to me the day I opened my grandmother’s tin box. It held recipe cards with prayers scrawled on the back of every one in her handwriting. She would never have called any of that a Book of Shadows, but that’s my point. Call yours whatever feels right, grimoire or journal or recipe tin. The word is just a word.
What actually matters is whether you can pick it up in twenty years and still feel the version of you who wrote it.
Mine sits on the shelf looking a bit worse for wear. The spells that actually worked sit next to the ones I quietly stopped using. Pressed herbs have started staining the pages around them too.
It feels smaller and more ordinary than the word “grimoire” suggests. The book of spells label fits better when I flip through and see all the bits that never quite left the page.
Grimoire = cookbook. BOS = diary of what you ate and how it made you feel. Which means mine is basically a cookbook with “this recipe made ME CRY” scrawled in the margins, so maybe I’m doing both wrong.
The simplest way to sort it is to pull out your book and split the pages into two piles. One for reference stuff you’d happily share with anyone, and the other for personal spiritual documentation you’d only show your coven. That second pile is probably your BoS material.
My own BoS looks pretty different from what you’re describing, but that’s kind of the point.
Keeping Mirrors, those personal reflections and dream journals, often gets lumped in with what folks call a Grimoire. Traditionally though, your Shadows holds the instructions, while Mirrors captures how the work actually moves through you.
Grimoire comes from old French for “grammar.” So at its root, it’s literally about studying language. Make of that what you will. Book of Shadows is a different story, though. Pretty recent, actually. Gardner coined the term, and I haven’t come across anything suggesting it existed before his practice, though I could be wrong on that.
One is personal to you and doesn’t need to be neat or structured (though you should always treat it with respect), while the other should be done painstakingly slowly, carefully curating only the things that matter most and are often contributed to by multiple people over time. Sometimes over decades or even centuries.
I think the distinction might be simpler than we make it. Grimoire as recipe book, BOS as the whole messy journey? At least that’s how I’ve come to see it.
The privacy piece is interesting. People publish grimoires sometimes, but a book of shadows stays personal, your trial-and-error experiments, your feelings during rituals and meditations, all of it. Maybe that’s why yours evolved the way it did.
Outside of traditional initiatory Wicca, pretty much any witch’s personal magical journal gets called a ‘Book of Shadows’ these days. Dreams, pressed herbs, whatever you want to keep track of.
Your house catches fire and you can only grab one book. If you’d grab the one with the working spell instructions because you could rebuild the feelings from memory, that’s your grimoire and the other is your BoS. If you’d grab the one with your dreams and ritual impressions because spells can be re-copied but those moments can’t, then that one is your BoS.
You probably can’t choose though. That’s why so many of us just smoosh them into one book and call it a day.
My first ‘book’ was actually a shoebox of loose papers and napkins with scribbled herb notes, along with the back of a school notebook. I didn’t know either word back then. I miss the days when it was just mine, untitled.
The labels came later when I went looking for community. Sometimes I wonder if naming it changed how I wrote in it.
