I will not quote spells here, I'll just make a few comments here for those who are new here and began to learn about spells and these stuff. Some here ask about what is, how to cast or how to create an spell.
I think the better way to start, is 'to start with the basics'. The stories about wicca / witchcraft (differences). How it was created, books, references, etc (the forum has many sources to research). One of the things I learned during my studies, that magic is not practiced simply quoting verses well written, or that rhyme, but with your mind and spirit.
Spells is not a cake recipe that can be used by all people. Some spells work fine or not, with each person. I once read, (I can't remember by whom it was written) but said that some spells may not happen for various reasons, some of them, very obvious.
Imagine you trying to cast a rain spell or wanting snow in the desert? There are several reasons to not happen. The same to invoke spirits, for example, when it refuses to appear (maybe lack of maturity or others things).
The idea is, magic consist in studies, attempts and love with what are you doing, long learning and practicing. So, don't be disappointed with a few failures, and don't want to skip the basic, to feel lost in the advanced. Seek to learn the basics and feel free to share your questions in the forum.
