Birthday Candles are excellent instruments for meditation and for casting intentions.
These little candles burn in under 5 minutes, you can even rub a little good luck, prosperity, money or Love oil(s), this kicks the intention up a notch. You can gaze into the flame as it burns all the way down, without going cross eyed or loose focus as with larger candles. You can even say a mantra or set of words over and over as you focus on the light of the flame. I find that this ritual, works wonders especially when you are trying to shift stubborn, blocked and stagnant energy or when just asking God for some help.
