About a year ago, I bound someone to me using a sigil I created. No spirits were involved. I can no longer stand this person and I want nothing to do with me: zero communication and zero presence in my life.
How do I undo my magick?
I’d go with what DarkestKnight said here, since you are practiced using sigils for this, you are likely to have an easier tie of it doing the same to break it.
Just create a sigil that says “you are free” and activate it the same way you did the first.
I personally prefer avoid negatives, like “you are not bound” because they can be read as positives by your subconscious/the universe, which doesn’t see the “not” bit very well. Focus on “absent/void” rather than “not present”.
