Invoking
Invoking is a form of voluntary possession. When you invoke a deity or being, you’re not asking it to come hang out, you’re inviting into yourself, and that god or goddess will manifest through a human host. The ritual of is an excellent example of invocation of deity.
Typically, if you’re new to spiritual practices such as Wicca or Paganism, most people will advise you to hold off on invoking deity until you’ve learned enough to have a good handle on what’s happening. It may be a good idea to focus instead on evoking, and communing with the gods, before you go inviting them to take control of you, even if it is just on a temporary basis.
