I love candle magic its relatively simple and its a wonderful addition to any spell.
I also love tarot.Its a simple means in which to connect with your subconscious and the world around you to get the answers you seek.
The both of them can go hand in hand together.They both utilize the energy around them for your desired results.Energy from candles can be used in your spell work,plus you can mark candles(write on it,put oils)I draw runes and place oils on mine.
I use tarot to get a gist of whats happening both physically and emotionally to people.
I think its a good idea to pickup on either one of them if you wish.As they are both useful and wonderful to learn as well.
p.s You can message me if there is anything you wish to know.Or anyone whom has knowledge in the area you seek.
