Hold a pink candle and charge it for future spells by visualizing you and your lover in a happy loving embrace. Put the energy from this vision into the candle. Then say out loud,
We will always love each other. May the Goddess and God grant this for the good of all.
When problems arise in your relationship or you need self-confidence, take out the candle on a Friday during a waxing moon. Anoint it with love oil made from rose petals, and various essential oils specific to love attraction. Put some oil on your index finger, and beginning in the middle of the candle, run your finger to the wick end. Then repeat, rubbing the oil down to the bottom of the candle. Light the candle and let it burn down completely and go out. (Always make sure the candle is safely guarded and away from animals and children).
Although this love spell does involve some pre-planning (by having previously charged the candle), I don’t see why it shouldn’t work by charging it and performing the spell shortly thereafter. The trick will be to summon up the appropriate feelings of love if you’re not in a particularly loving kind of mood.
