w0wpow3r: To answer your question,yes, there is be something more to "drawing out the devil" than that particular belief. Personally, I believe in one God who created the world and all that is in it – and that includes plants, animals, minerals (even lodestones) and humans. However, I do not believe that God created a magnet, such as a lodestone, to "heal" someone or cast out the devil from a person. The Bible says that demons are only cast out through the name of Jesus Christ. Jesus Christ is God's Holy Son who is "the Way, the Truth, and the Life. No one comes to the Father (God in Heaven) but through Me," as quoted from John 14:6. Jesus Christ is our only true source of hope, peace, and ultimately, forgiveness of our sins and eternal life in Heaven after we die here on earth.
So, being God's Son, Jesus is the only true and perfect human being that ever walked this earth. The Bible explains that Jesus came to earth in human form, born of a virgin (Luke 1:29-35), lived about 33 perfect years, making no mistakes whatsoever, and eventually died on a cross in the place of a murderer. Why? Through His death on the cross, Christ would ultimately defeat sin, Satan (the devil), and eternal death (life experienced in Hell forever and ever). He died, was buried for three days, and after the third day, God raised His Son up from the grave. He is alive today and forevermore living with God the Father in Heaven!
So what does this have to do with anything? The Bible explains that all who believe in Jesus Christ and follow Him as their Lord and Savior will not only have the eternal gift of Heaven after life here on earth, but also, Mark 16:17, Jesus says, "and these signs will follow those who believe: In My name they cast out demons..." Satan (who is the devil), and all of his demons are afraid of no one here on earth, but they are afraid of God and His Son Jesus Christ. Even at the very mention of the name of Jesus, the devil flees and all his demons with him. Anyone who "talks to the devil" or his demons (most commonly, and mistakenly, called ghosts), or anyone who practices anything pertaining to "talking to the dead" (which is actually talking to Satan's demons, called his followers), is practicing a lie.
If they do not quit these practices and call out these demons in the name of Jesus Christ and believe on His name in their own hearts and confess to God Himself that they are in need of Jesus in order to go to Heaven (since we cannot do it on our own), we are going to spend forever and ever in Hell after we die. So what about those who claim that they see their ancestors or other relatives who have passed away and have communicated or are now communicating with them? Well, these "ancestors" and "relatives" are nothing more than Satan's demons who are master deceivers. If they can, they will fool anybody by taking the form of a loved one or anyone who has died, and "communicate" with them. One should find it incredibly scary, and perhaps exaggerating, to think that they are communicating with Satan and his demons themselves, but they are. When they think they are "communicating with the dead", they are actually communicating with the devil, Satan, and all his followers(demons). And all who practice these things are destined to perish in Hell forever, because they rejected God, Jesus Christ, and His Word, which is Truth, the Bible.
So, in summary, the devil cannot be "drawn out" except through the blessed name of Jesus Christ.
"Therefore God also has highly exalted Him and given Him the name which is above every name, that at the name of Jesus every knee should bow, of those in heaven, and of those on earth, and of those under the earth, and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father" (Philippians 2:9-11).
