Evening all,
I'm really sorry for my ignorance, but I'm hoping to reduce my lack of knowledge somewhat by asking a few of the burning questions I have here and, if anyone is kind enough to answer, then I'll be immensely grateful. Again, terribly sorry if I come across as ignorant or otherwise rude; I'm just a little new, I guess. Here's the stuff I can't get my head around/ find info on:
1)So, firstly I was wondering if a Witch has to commit to a tradition and area of Witchraft and, if so, do some of these traditions involve initiation, similarly to some Wiccan practice?
2)I understand there is Eclectic Witchcraft. How much of practice is mish-mashed together? So to speak,would you take from any tradition you felt interested in, or a select few?
I hope these are clear enough. Thanks to any and all replies made, and hopefully these questions arent too blunt or vague :)
