Burn green candles on Fridays, the day of Venus. Her energy is not like her brother Mars. She’s receptive and inviting, bringing in more money, improve your luck, or possibly make a situation (or yourself) more fertile, burn a green candle. (And of course, if you can, do some earthly or practical work towards those intentions.) If you work with chakras, the green candle is said to help open or unblock the heart chakra.
