Once you have opened the sigil, do you keep it somewhere until the goal is accomplished, or do you have to take it with you wherever you go?
Both have been recommended in books.
I would say, it depends on the intention. If it was intended to affect interactions with others, maybe take it with you when you’re having those interactions. If it was meant to affect something general in your life, leave it in the house, maybe somewhere you won’t look at it, but that doesn’t diminish it’s importance, like, under a vase on the mantel.
Thanks for your advice!
