As a Witch I have a hard time believing stuff from the net. Most people are just out to get your money. While I do believe in magick and believe spells work, unless you know the witch/pagan/wiccan personally I would steer clear. I could easily promise you to do a spell for $20. You pay pal that to me, I send you a gem in the mail that I probably have dozens of and then tell you I did it. No guarantee I did anything but sit on my computer and play World of Warcraft.
Hey Aayla! Nice to meet a fellow witch!
I am a witch as well, and have been doing a lot of spiritual work on myself for years. My love life, money, living conditions, relationships, and quality of life have all improved drastically as a result of the work, but I will also occasionally have others cast spells for me to make the work more powerful.
Before I do any work on myself or have others do work for me, I always do some form of divination to determine if the spell, ritual, or spiritual work would work for my request. Sometimes I'm told no, try another way, other times yes, and sometimes no it's not meant for you. And in all cases, the divination is right.
So, through divination, I discovered that these ladies would be able to help me get pregnant with twins. When asking if it would benefit me to have them cast spells for weight loss, divination told me no...try another way. Lol...
I say this to say: I have been taught by Elder Priests and Priestesses to always use some form of divination before any spell or spiritual work to determine if it will work for your request. That way you don't waste your time or energy. And also use divination afterward to determine if your spell or spiritual work was successful.
