If you're weak willed, and you invite a wolf spirit to join you, please ensure that the spirit is not malicious. That's something people don't seem to get, not all spirits are friendly. If you're also inviting that spirit to take up residence in your talisman, be prepared for done very ill effects or energies. If you do happen to take in these negative energies, or develop negative traits, be sure to expunge the spirit, and cleanse your talisman, as well as yourself.?
