Without going into so many identifying details, there was a situation where I felt I needed a buffer between myself and another person several months ago. I needed a safeguard, a warning, a "hey, stop that!" to go between me and an individual. A reflex, when you touch something prickly or sharp, and you recoil. You don't touch it again without a really good reason. I wanted distance, and I wanted that person to realize that I was serious, and their treatment of me hurt and shouldn't happen again.
More generally speaking, another component of the protection jar was to stop people from intruding on my schedule - I felt really crushed by expectations and needed a little more sensitivity in regards to time. I'm not always good at standing up to people, and I didn't think that this particular person would be empathetic to me.
I collected all of my components, and the jar was made on a full moon, so it could work during the waning moon as a banishing. The jar I used was a simple spice jar (now holding cat whiskers that the girls have lost through normal shedding).
Into the jar went thistles for protection and severity, mint for invigoration, yarrow for protection of psychic boundaries, a charged quartz crystal, and "Please Go Away" incense that I was gifted by a Silver Circle member over the summer.
A note: the thistle, mint, and yarrow were all grown organically and locally. Since I wasn't ingesting any of these items, the argument could be made the need for them to be organic isn't strong. However, I feel committed to using sustainably and joyfully grown, small batch plant materials whenever possible. The plants are more powerful and happier in their soil, and I feel a difference in these from the imported alternatives.
I don't have any photos of the finished jar - I'll leave that image to your imagination. Making the protection jar was cathartic for me, and I have no doubt that there was an affect. This was witchcraft as recourse.
What protections have you done for yourself?
