When I decided to write this, it seemed simple. Take a few minutes to tell what a spirit animal is and what it does. Now that I'm doing it, it doesn't seem so simple. What follows is my feeling and impression from working with spirit animals. Your experiences and impressions can be very different.
The Native American often found a spirit animal guide through the vision quest. The vision quest usually required isolation, usually with fasting in a prescribed manner, for a number of days until an altered state of consciousness was attained. In this altered state of consciousness, one became more open to other worlds and other world energies and would receive a message or sign from one's animal.
There are several differing criteria as to what constitutes a valid method of contacting and recognizing a spirit animal. Besides the traditional Native American vision quest, dreams, visions, meditation, spirit animal retrieval by a shaman, retrieving your personal spirit animal in a journey, consulting medicine tarot cards or a special interest in a particular animal are all methods used by various people to locate and define their spirit animals. The method that works for you is the valid method for you.
Spirit animals can be actual animals such as Bear or Deer; they can be extinct animals such as Mammoth or T-rex; they can be legendary animals such as Dragon. Spirit animals can be animals that swim, fly, crawl, or walk; there is no limitation. You may have noticed I refer to the spirit animals as Mouse and not as a mouse. The spirit animal repersents the energy of all the animals of that species.
No spirit animal is better than another; Dragon isn't better than Mouse, just different. Different spirit animals have different methods of doing things and bring different wisdom. Some say domestic animals have less energy and power than wild animals but my most exciting and adventurous journeys were in the accompaniment of a domestic animal. They are guides and teachers if you're willing to learn from them. I retrieved several different spirit animals for people including Buffalo, Camel, Antelope, Mammoth, and Black Panther. Everyone who received one of these animals felt they were the right animal for the time and were very excited and happy to get them.
I visit my spirit animals in the lower worlds, the worlds I enter by going through a tunnel to enter NOR. I meet at least one of my spirit animals when I exit the tunnel. It can be any of several animals working with me or, in special instances, more than one. We go on trips, talk and do things. While I personally consider the upperworld entities I met to be teachers, I consider the lowerworld spirit animals to be companions, friends, fellow adventurers. They are the action guides
There are several ways to discover the lessons or messages of your spirit animals. One method is to study the characteristics of the animals by personal observation, in factual books, in legends, and in books giving interpretations of the animals. All of these sources of information, I've found, may round out understanding but are no substitute for actually working with the animal. Another method is to journey or meditate and ask the animal directly. When I bring back an animal for someone, I always ask what the message of the animal is for the person I am retrieving the animal for. I find the messages often differ from the interpretations of others.
One way I interact with my spirit animals is to take them on walks. When I go for a walk, I just throw out the invitation, "Anyone who wants to go for a walk, come on." Usually I sense one or more animals walking with me.
I sometimes dance my spirit animal. It works for me. It takes about 20 to 30 minutes. Intent is the main thing. Feel free to use, modify or ignore this ceremony as you see fit. I think it is best to make your own ceremony or make this ceremony yours by changing it as you feel fit.
