First of all hello,
I am a solitary witch who needs to share something...with my likes.
I created a spell in which it lasted for 7 days and on the 7th day I lit my chosen candle and poured in my intent. The candle stayed lit for 8 hrs exactly. Right before it went out, the glass beneath cracked and broke into 3 pieces. I like to think my intent was so strong that that's what broke the glass, but my boyfriend thinks it was only due from the heat of the candle. Is there anyone who can share a similar experience? Or just let me know your thoughts on this?
Blessed Be.
