I see many people, saying: "Why doesn't this spell work?!", or: "How do I make spells?". Now, it is important to know that spells are very personal. A spell is made for a specific purpose, and in the creating process, the feelings, personal experiences and energy of the creator will be put in the spell. So, you might understand that the spells on this site will not always work. I suggest copying a spell, and then edit it yourself, or (the best option, I think) create an entirely new one, which isn't as hard as people think...
I don't know how it's written in the english version of the bible, cause I only read it in dutch, latin and greek, but it says that God created the human race as a copy of himself. So, shouldn't we be able to create and shape things then (for the christians among us)? That's quite funny, eh? Now, I don't want to continue with this subject, so I'll go on.
Creating spells, is the same as drawing, the same as writing a story, with one exception: it's not true, if you'd ask most people. You have to connect to the universe, and you'll know that it works fine!
Also, keep in mind that something is what you think it is, which makes the world around us quite weird sometimes. If you know this, that little sentence, you've got the key to change things. The world is, what you think it is.
And after those stories, we came to the subject of creating. There are various ways to create a spell, which is actually nothing more than a way to show that we know the truth about life. You can visualise, think, draw or any other way you see fit. You're the creator. Mostly, people use ingredients for their spells, so they've got a feeling that they have to do something in order to make the spell happen, which makes it easier for them to believe.
I hope this helped you, and blessed be.
