Many people involved in Pagan and Wiccan spirituality find themselves, at some point, worrying about magical attack. What if someone casts a spell on me? How will I know? What do I do? More importantly, how do I protect myself so that it doesn’t happen in the first place?
Well, first of all, relax. Chances are really good that you're not going to be the victim of a magical attack at all. Here's why: it takes a certain amount of skill and effort to magically attack someone with a curse or hex, and honestly, many people aren't interested in putting forth that much work, and of those, many do not have the skill level required for a magical strike. In other words, not everyone who talks the talk can walk the walk. That having been said, if someone is willing to put forth the effort and they have the ability to craft an effective spell, it's possible you could be the victim of a deliberate, concentrated attack.
Be aware, also, that in most cases, someone who tells you they've hexed, cursed, or otherwise put a spell on you is the one least likely to be able to do so.
