Fill your bathtub with water and scatter some fresh rose petals in
it. Light some vanilla candles and/or incense. As you lie in the water,
meditate on the image you would like to project and say these words:
"Earth, Air, Fire, Sea
Let the Goddess' beauty
Shine through me"
If you don't want to cast a spell on your own, I'd suggest reading my Reviews of Online Spellcasters and picking someone good from that list.
