I'm kind of new to all of this so I have a couple questions.
I understand that you don?t have to cast a circle before casting spells, so why would you if you chose to do so?
Even though I have no active powers I have had many life regressions when I was a little girl and have astral projected once by accident while meditating. Would I be considered a witch or sorcerer? I do not believe that I was born with abilities, but I have no idea how to explain these incidents when I was a child. I have been studying rituals and spells but haven?t cast anything except blessing objects, like the crystal I always wear. So I?m not sure what to consider myself. I still have not chosen a path for myself because I?m not sure about what I consider myself to be.
I was looking into Wicca. I understand that is a religion, but I do not see myself studying it and participating in the religious aspect of it. I happen to like what they belief in though and what it stands for.
I am mostly into healing and protection with a little soul searching thrown in. What path would you all suggest? Maybe point me in the right direction and I can take it from there.
I have read that spells are more powerful and likely to work if you say them in Latin. Is this true? And if so, is google translator a good enough translator? I would hate to get anything wrong. if I write my own spells, will the phrasing still be the same after I translate it?
Now that I have chosen to practice magick, do I have to worship any gods or goddesses or is this purely a choice?
Thank you for your responses.
