In some traditions of magic, you may see the phrase magical link or taglock used when it comes to instructions on spellwork. But what exactly is a magical link? It's essentially an item that is linked to the individual who is the focus of the magical working. In some traditions, this is called a taglock, but most modern Pagans use the magical link terminology.
Keep in mind that a taglock, or magical doesn't have to represent a human being. It can represent an animal, or even a place. In her book Everyday Magic, author Dorothy Morrison suggests using a magical link when you're doing a working to buy yourself a house. She says, First, find the home you want to own. Obtain a taglock from the inside perimeter. Nearly anything will work - a bit of carpet fiber, a paint chip, a shred of wallpaper, dust from the floor - as long as it comes from inside the house. Obtain a taglock from the outside property too.
