Here are a few good candle magick spells to add to your Book of Shadows, but if you're looking for love spells, there will be another page specifically for those coming up soon. Oh, but I already have 2 good candle spells on the Reunite Lovers page if you are looking to bring someone back into your life.
The Light of Joy
This is a household-type of spell that you use to reduce any tension that is becoming a problem and bringing in some happiness for the whole family (it works with roommates too).
You can do this spell on your altar but setting it up in a central place of the house is a better idea. Arrange the 5 candles in a circle. Set the crystal in the center, and then pile the basil leaves on top of it. Then light the candles.
Light the incense, and carry it through all the main rooms of the house. Take your time and let the smoke spread out. Once you've done that, return the incense to the place with the candles, and let everything continue to burn until out on their own. You should find that the tension and conflict should lift very soon.
Of course, if there are specific active problems going on in your home, you'll have to work them out before you can expect magick to fix everything.
A New Start Candle Spell
This is a good multi-purpose spell that can be used to give a bit of "oomph" to any new enterprise, whether it's a new job, relationship or just a new chapter in your life. It's an easy spell too.
Anoint both candles with some oil, and set them in candle holders next to each other. Light one of them, and describe some of the "old" things you are hoping to get rid of. Focus on that for a few minutes, and then use the candle flame to light the second candle. Snuff out the first one.
Now list some of the new things that you are hoping to draw into your life at this new start. Be optimistic but realistic too. Leave the second candle burning until it is finished. You can reuse the first candle in another spell if you want.
