What do I define a grimoire to be?
My personal definition of a Grimoire is, for want of a better term, a textbook; filled with all of the information I have collected from various sources as well as my own understanding of how things work and what they correspond with.
I use it to read over what I have learnt so far, and also to use the correspondence charts when using my crystals, divination tools, creating spells and anything else witchcraft related.
What do I define a Book of Shadows to be?
My personal definition of a Book of Shadows is a book in which I keep all of my active spells, sigils and crystal grids along with any of these that I wish to try out in the future. It’s where I put all of the practical aspects of my craft.
It’s also where I put spells I’ve tried that may not have worked as a record of my journey and where I need to improve or learn more about the related subject.
Why do I have both?
Personally, I feel having just one book filled not only with information but also with any active spells, etc to be too confusing. Because of this I have divided these two aspects into separate books. It just works better for me and my craft.
