Can someone help me sort the useful bits from the nonsense in this grimoire?

Most of this reads like general ritual prompts dressed up as firm instructions. A blessing for a book can be a perfectly personal way to mark it as yours, but there’s no universal rule about breathing over it or anointing its “colour corners.” That phrase is also vague enough that I’m not sure what the writer intended.

Moon water is similarly a spiritual practice, not a special kind of water with established physical effects. If you make it, use a clean, closed container and don’t leave it somewhere it could get dirty. I’d skip drinking it unless you’re confident it stayed safe to drink, and avoid putting unknown oils in bath water or on skin.

The protection ritual has a few practical red flags. An unattended candle near the front door is a fire risk, and burning herbs can bother anyone with asthma, pets, or sensitive lungs. Salt on floors can also be a nuisance around some animals and surfaces. You can keep the parts that feel useful, like a spoken intention or ringing a bell, without using flame, smoke, or scattered salt.

Also, the list repeats “bell or chime,” and “white sandle” looks like a typo. That doesn’t prove every idea in the book is worthless, but it does suggest the instructions were not carefully edited.

I wouldn’t treat a grimoire as an authority just because it calls something a ritual. Practices differ, and a lot of people build rituals from their own beliefs and traditions. This book’s language is pretty generic, so I’d use it as a set of optional prompts rather than a source of rules. If a step feels unsafe or doesn’t fit your practice, leave it out.
