I'm surprised sometimes when little operations cause so much havoc.
For instance last wednesday I performed a small operation to consecrate new wicks and oil for my holy lamp complete with prayers, psalms, and spirits/names of power. Later that night my spouse terrifyingly woke-up to a television mysteriously turning on by its self in the middle of the night. I had fallen asleep on the couch and was not in the bedroom when this occurred. Such an event wouldn't have scared me so much, but I was quick to console my lover, and go back to sleep in our bed.
This all happened hours after I consecrated the materials. It makes one wonder if the actual consecration of the materials happened after my actual ceremony when the TV phenomenon happened or just was it just a spirit-based side-effect later on.
I am not a stranger to such things when I summon an entity. The spirits sometimes actually disturb my space for days, weeks afterward. But after a tool consecration?? Interesting.
