There's a lot of talk about spirit guides and spirit animals, but I cannot imagine such a guide, or animal allowing someone under their guidance, protection, or watch to be hexed or cursed.

I guess the best way to remove a curse is by being powerful enough and connected with the friendly spirits to not have been cursed, or hexed in the first place. Perhaps it might be a good idea to attain such power and 'friends'

Even by asking such a question in an overly open manner is advertising that there is a lack of knowledge, power and spirit helper. It could open one up to harm.
