Animism is a religion that appeases and seeks favor from demons.  The past demon-inspired behavior and demon-devotion behavior by the ex- Shaman practitioner / Christian adds another level to cleanup.  

The first step is to ensure you have the authority to do the cleanup. Say this aloud, "Our Father who art in heaven, I receive Jesus Christ of Nazareth, your Son, to be my savior and master. I will trust and obey him for the rest of my life.   Amen."  You are now a Christian.

Classes of spirits:

For each of the above classes of demons:
1. "I renounce _______ in Jesus' name. I break any seals or creative powers over any charms dedicated to _______."
2. "I break the power of demon-inspired or demon-devotion behavior given to _______ in Jesus' name."
3. "I command _______ to leave me, my family, my property, my finances and those who have helped me in Jesus' name." 
"Amen."

Now finish with the following prayer:
"Our Father who art in heaven, open my eyes to see any objects I might have that are still contaminated that must be gotten rid of. I unstack the Kundalini in me down to elementary demons.  I command the elementary demons to leave now.  Father, fill me with Your Holy Spirit in all the areas that these demons have left. Protect me from sickness, harm and accidents. I thank you for all you have done for me, in the true Jesus’ name.
 Amen."

You are now a sanctified Christian.
