What you need:
A large bowl
A wooden spoon
Paper (in a square, preferably) and ink
A candle (the colour should reflect the wish)
An old plate
As many of the following as possible: Cinnamon, basil, clover, ginger, marjoram, tea, catnip, jasmine, ginseng, lavender, pine, sage, cloves
This is a simple spell but its effectiveness relies on your will, so you may want to create a more complicated ritual.
Beforehand, place all the herbs in a bowl and crush them down with the spoon - you can use a mortar and pestle if you have them. Then once crushed and powdered strain them through the sifter to create a powder without any large pieces.
Then prepare for the ritual. If you wish to make the spell more effective, the time of day, moon cycle , day of the week, and so on should reflect the nature of the wish.
Prepare your ritual and sit down with the paper, lit candle, plate and powder in front of you. Write the wish on the paper (you may like to write it down somewhere else as well - you need to have the words later!) and make sure they are heartfelt. Fold the paper three times each way (across and down). Then take the paper and set it alight with your candle. Let it burn on the plate until it has turned to ashes. Once it has, mix it with the herbal powder to make a very specific wish powder.
This wish powder should be taken out on preferably a windy day (you will know if the day is right) and scattered while chanting the words of your wish with feeling. Then wait for your wish to come true. While you're waiting, do as much work as possible towards your goal. For instance, if you're looking for a new apartment actively search the newspapers, network with friends etc. As above, so below, when magick is working in the Astral you must also work in the physical in order to ensure manifestation of your wishes.
Goddess of the Moon so fair,
I ask thee harken to my prayer.
May that which I desire be granted,
With sincere intent, these words are chanted!
