For discussion purposes I 'divide' magic into two broad categories, thaumaturgy and theurgy, the thaumaturgy being measurable 'miracle working/money drawing/physical healing/etc' and theurgy being "spiritual development work".
I've posted some about those things before, like here, and here, and here, and here.
Now, probably everyone agrees that the theurgical magic you do is tied to you. Cuz who else would it be tied to? I'm also assuming that you probably use your magical tools to do this magic when use of them is appropriate.
It has come to my attention that some folks don't think that 'everyday' magic you do is also tied to you. As in "Blood anoited [sic] tools binds magic to you and your bloodline. Not wise if you plan on to use the tool for basic everyday spells." This was a response I got on the Witchcraft, Paganism, and Wiccan page on FaceBook. I'd link you, but, due to people posting complaints about the regular plagiarism there, posting by all but the admins is now closed so getting at MY post is impossible.
Darlings, your tools are ' yours' because you and then are bonded together. that's a fundamental part of your being able to use them fully. If you are REALLY bonded to, say, Wand, then you can use your finger and not a pretty anointed with ANYthing stick. And, guess what - your flesh, blood, and bone makes up that finger.
ALL MAGIC YOU DO IS TIED BACK TO YOU. That's how we trace back hexes to who they came from. That's how the "Law of Return" works, to those who believe in that. That's how the 'three fold law' works for those who believe in that. That's how your senses work, for that matter - that tree I'm looking at is sending things that ENTER MY EYE so I can see it.
If you think you can duck being tied to your magic by NOT being 'blood tied' to your tools, you are fooling yourself.
