I love to light candles for clients, so much I do this service free for VIP clients. Lot's of times I will light a candle for protection, love or money. I never do anything evil. I just say my prayers over candles as though God is watching me.
I often get asked by clients what color candle should they burn. Here is an illustration on choosing a candle that is right for you depending on the situation or wish you may have. Remember to always keep it positive and good chance the universe will bless you.
