If it broke it depends on the situation. If it was a candle for protection, peace or a happy home I would take that as a bad omen. Same for reuniting love. If it was a road opener (abre Camino) you could take it as a sign that you broke through your obstacles. It could go either way with money. If it was to bring more money your way, bad news. If it was to get rid of a money related obstacle then it could be good.
It’s never a good sign when saint candles break or their faces burn. That means they don’t want to work with you.
In a breakup candle (for those of you into that thing, no judgement and I’ve seen it successfully done) a break is a good thing.
I’ve had some horrible explosions lately, but my situation is bad lol.
I’d also recommend a sweet jar for yourself, to draw love and attraction.
BTW it will mess with your head if your intentions aren’t clear, or you aren’t protection yourself. Burning palo santo or real sage, taking hyssop baths and reading psalms are great protection tools. If you’re catholic find a saint that appeals to you and develop a relationship with them. Ask them for guidance and protection.
