Part of what caused me to think of this was a client who, as of late, has decided that she is going to undertake a new path in her life. She and I have talked at great length, and she has decided to devote her life in service to a specific deity, though she was concerned that her doing so might have been improper. From what I found, being the intermediary between God and client, was that she had already received more than enough invitation from the aforementioned. He had been showing up and calling to her for years, even if she hadn't had any idea what was going on.
That, of course, brought me about to write this post. There are times where some of us may get called towards a specific direction or practice without any idea as to why the hel it happened. Sometimes that may be scary, but I think that its important to realize that this isn't necessarily a bad thing. In instances like this, one is being initiated by the spirit themselves, rather than by some human individual who claims to be doing it. If you are lucky enough to be called in such a way, I'd urge you to heed the call and go forth. There's probably something to learn from such an endeavor, and if you aren't sure if that's the case, divine, or have someone do it for you.
My guess, for the coming year, is that this will start happening more and more. Should this happen to you, go forth and attend the deity, and most importantly, make sure you pay attention and learn something. When you're called in such a way, the rules of initiation don't apply to you in the same way!
