Ever wish that you could write a spell and you think that you can't? Think that way no more, everyone and ANYONE (no matter what religion you follow) can write a working spell! How? Here's how I do it, you may add and take out what you wish,but always
make spellwriting and casting personal! A spell should be one's personal, spiritual involvement with the Lord and Lady.
How to write a spell:
Its always nice to have a book with correspondences in it. I used to use The Pocket Spell Creator. It has correspondences for herbs, days, colours, crystals, oils and food! It also has chants for every type of spell that's commonly used. You also might want to explore what things the Gods and Goddesses cover, if you are the type to call on all Gods from all pantheons. If not, research the Gods and Goddesses of the pantheon you feel closest to. If you don't have access to books like that, the internet is always good, and you can cross-reference what herb/crystal/oil does what.
1. What kind of spell do you want to cast?
It's always good to have what kind of spell you want to cast in mind. I think that's a fairly obvious point and I'll leave it at that.
2. What day of the week would it be best cast on, and under what moon phase?
Timing isn't everything, but if you are the type to time your spells to maximize the potential of it happening, find the best day to cast your spell. These are what I usually use:
SUNDAY: Yellow, the Sun and solar deities. It is associated with magic dealing with: authority, divine power, friendships, healing, learning, reason and world leaders.
MONDAY: White, the Moon and lunar deities. It is associated with magic dealing with: cooking, dreams, family, the home, intuition, medicine, spiritual growth and the ocean.
TUESDAY: Red, the planet Mars and the god Tiw. It is associated with magic dealing with: athletics, competitions, conflicts, courage, hunting, legality, logic, physical strength, politics, vitality and war.
WEDNESDAY: Purple, the planet Mercury and the god Woden. It is associated with magic dealing with: communication, divination, education, mystical insight, resourcefulness and self-improvement.
THURSDAY: Blue, the planet Jupiter and the god Thor. It is associated with magic dealing with: dedication, endurance, faithfulness, legal matters, loyalty, luck and money matters.
FRIDAY: Green, the planet Venus and the goddess Frigg. It is associated with magic dealing with: art, fertility, love, music and pleasure.
SATURDAY: Black, the planet and god Saturn. It is associated with magic dealing with: banishing, change, death, motivation, reincarnation, understanding and wills.
The phases of the moon play a part also. I personally believe it to be different aspects of the Goddess looking down upon me, so I try to fit the aspect with the spell I am to do. Maiden for the waxing, Mother for the Full, and Crone for the waning/dark/new moon.
5. What kind of spell will it be?
This basically means will you be making a candle spell, a pouch spell, or just a traditional spell? (by traditional I mean, a candle with a colour that corresponds to the spell, a few loose herbs to burn on the charcoal (which also correspond), and whatever else you would use in a spell)
4. What ingredients will you incorporate?
This is where it becomes tricky, because many sources say different things for herbs and crystals. Find one source that you feel to be right, and stick with it, because many places will tell you different things, like I said.
Once you have a good source, list which herbs have properties that correspond to the spell. Lets say I wanna do a love spell. I would have in my list: Geranium, Rose, Ginger, Coriander, etc.
Once you have the list, begin to cross out which herbs you
don'thave. Soon you'll have a list of the herbs that you have, (or crystals, oils, candles, whatever you are going to use in the spell). From this list, pick out a specific number that corresponds to the spell. Say, once again, your doing a love spell. I would only use two herbs, one masculine and one feminine, in the spell. (If you are homosexual, I would choose two herbs of the same gender) For luck, I would use 4, like a 4-leaf clover

Once you have the list of what you will use (and you have!), you may begin the next step.
5. Writing the chants and calls
If you are one to cast circles, you can write your own personal callings to them, asking them to lend their power. If you are creating a spell for love, then you can ask fire to bring desire, water to bring true love, air to keep your head steady, and earth to ground you. If not, thats fine too. Remember, this is your spell. Make it yours!
Rhyming. I know that a lot of people have a hard time with it, but I use rhymezone.com's rhyming dictionary

So I have a rhyme for everything

If there is no rhyme that makes sense, its fine. Rhyming is not needed for a spell. The only reason most do, is that A) the chant is easier to remember, and B) rhymes just roll off your tongue and sound nice when spoken a loud. This, according to many, appeals to the Gods and Goddesses. You may rhyme or not. It is wholly your choice.
But one thing to be sure to do is to say EXACTLY WHAT YOU WANT. Try not to be vague. Try to give as many details as you can. This avoids the spell going wrong, or backfiring.
6. Crafting the spell
Now that you have the list, you can start planning out the details. What will you do first in the spell, call the deity that you are working with, or will you light the candle first? Let's say (here I go saying it again) you are crafting the love spell. You have geranium and you have basil. (female and male respectively) You have 2 red candles. And you have a bowl of water. You have chosen Aphrodite and Eros to call upon. First, I would call to Aphrodite, then I would light the candle, then call to Eros, and light the other candle.
This is where symbolism comes into play, also. You can draw a heart around the candles with the herbs, and slowly bring the candles closer together, as you bring your lover closer. Remember this:
Symbolism helps you work the spell strong. Why? Because in our minds, we already have symbols set for certain things and feelings. An eye for psychic power, a heart for love, a dollar bill for money. Once you start working your mind by bringing up these symbols, you start working the spell before you even start casting it.
7. The final draft of the spell! *FINALLY!!*
Now that you have all the details, now is to write it out and fix anything that you see that doesn't seem to fit. This is what my spell would look like (and yes, if you want to copy this is your BoS, feel free ;P)
The Heart of Aphrodite spell
You will need:
2 red candles
dried red rose petals
dried basil
1 red ribbon
Timing: Best cast on a Friday, 1 week before the Full Moon (even better if the moon is Full on Friday!)
1. Cast the circle.
2. Light the first candle, saying:
Aphrodite, hear my call,
head over heels I wish to fall!
3. Light the other candle, saying:
Eros, Lord of love divine,
Bring a lover true and fine!
4. Sprinkle the herbs in a heart around the two candles. Leave them to burn for 15 minutes.
5. After 15 minutes, move the candles 2in apart from each other. Now say:
Closer, closer, my lover moves to me,
Apdrodite, Eros, hear my plea.
6. Wait 10 minutes, while waiting, see your lover (not anyone specific, but a shadowed figure) coming to you, and loving you how you wish them to love you. See them being faithful and truthful.
7. After visualizing, move the candles together all the way and say,
Goddess and God of adulation,
Bring me a lover of divine creation!
So mote it be!
8. Let the candles burn down. After they have burned down, take all of the wax and herbs and bundle them together in red cloth, and tie it with the red ribbon. Bury outside your front door.
I know that its pretty vague, I will be adding better details later, if needed. Also, if you have any questions, feel free to post!
