Shadow work isn't witchcraft. Shadow work is psychology. It was invented by Carl Jung, a psychologist, as a form of psychotherapy. It's literally early 1900s psychology, which, by the way, now in year 2025, is quite a bit outdated.
Understanding your own underlying desires, emotions, intentions, and experiences, none of this requires shadow work to accomplish.
You do not need to do shadow work in order to embrace who you are entirely and not just on the surface.
Everybody is different. Everybody learns about themselves differently, discovers things about themselves differently, self cultivates differently, grows and matures into versions of themselves differently. Growth, maturity, learning, living, experiencing the world, these things take time, lots and lots of time, and practice. There has never been a one size fits all for human development. Developmental psychologists have written no shortage of books and papers on this subject alone. Shadow work isn't some therapeutic silver bullet that'll solve your problems, give you a boost of mental health superpowers, voila, epiphany, self realization, you're a better witch. In fact, nothing will magically do this for any of us. There's no rushing life experiences and learning processes. There are things that simply take time, and work.
I've been a witch for 13 years and I've never done shadow work. I have, however, done nearly a decade of trauma recovery therapy. Trust me, by this point, at age almost 38, I know myself and why I'm a witch pretty damn well now. It's been a long while since I've come to learn what I'm capable of and why.
Do you know the damage shadow work can wreak if not done tactfully, carefully, with enough knowledge and understanding, and preferably guided by a mental health professional who knows what they're doing and with a good amount of trauma treatment experiences on their hands? People have ended up with PTSD, and people have had existing trauma disorders worsened, by jumping into it alone, unsupported, uneducated, not knowing what they were getting themselves into, not at all prepared for what would be brought to the surface too much, too quickly, too soon, way before they were ready, because some random witches on the internet who don't even understand what shadow work actually entails got into their heads that to be witches they must do shadow work.
If you're actually interested in this topic, then I recommend reading some psychology books, especially on the history of Jungian analytical psychology.
And by the way? You have no right, no place, whatsoever, to "enforce" anything onto any aspect of anybody's practice, spirituality, life, period. What works for you doesn't work for everybody. Your way of doing things isn't the right way for all.
So mind your own craft. Especially since you yourself appear to be misinformed and have some learning to do.
