Thank you, I have had a lot of trial and error actually and this is what just fell into place in my late 20’s and the system was honed over the years.
The love of reading, all things books and journaling is something I have done since I could nearly write — it was my escape and so personal and something I value more than any other inanimate object(s) - sounds like you have that ‘bug’ too.
The kicker of it is, is that most people don’t suspect anything and don’t read things I ask them too, let alone read things I don’t lol. So even hidden in plain sight is sometimes hidden for people you are around that don’t read or aren’t snoopy like that.
For my comrade witches in the broom closet, what we call the journal you have is a Commonplace Book or Journal which is something that dates back to Aristotle and the mid 300s BCE! Once you look into commonplace books, they are literally everywhere on the internet and YouTube and you can’t unsee how many there are! I love this ‘kid’ on YouTube and follow him and he has an episode I like on the Commonplace Book, but I’m sure that is what you are describing that you already keep! Witches back in the day coded their books with discreet sigils or drawings so that if anyone saw them they would not understand, know or even suspect anything ‘witchy’.
I write for those that couldn’t. That inspires me. I honor my fellow lights in the world in the future, now and in the past who are called by many names and persecuted for what they believe and what they do and practice - the mages, healers, truthtellers, magickcians, herbalists, bards, fortunetellers, gypsies, lightworkers, soothsayers, sorceress/sorcerer, enchanter, hag, crone, harpy, battle-ax, she-devil, fairy, pixie, and yes WITCH and there are more names I left off than put on this list. Interesting enough, everyone and I actually mean EVERYONE does witchcraft in subtle ways and not so subtle ways, and as long as I’m subtle about what I do, nobody cares or pushes anything as long as I do not push it either. Nobody wants other beliefs thrown on them. I don’t want any of them to “do me” either, I do me just fine - I am not here to save the world or make people believe anything - I am here to live, love and be happy and be the best person, partner, mother and friend I could be.
I just want to be left in peace and all of us can relate to that.
