Any ritual that would help you find a spirit animal is probably not one I'd take from an anonymous user off of a website.
That being said, in Vodou, something similar, though not the same, is Met Tet, or a master of the head. This can be revealed to you through a specialized, in-person reading. Usually a Lave Tet, a cleaning of the head, is done as well. This is an all day affair about which you won't know much unless you under take this ritual, which can be done by anyone of any practice. Though speaking to the Mambo or Houngan who will be doing this beforehand and attending a Fete or two is a good idea. Ask as many questions as you can think of and be wary. There are many who will promise and then run with your money. YES it will cost money. You pay for money, materials, and time! Just a thought.
