An altar or shrine is a place where divinity meets humanity or the visible meets with the invisible to forge evil demonic covenants with evil spirits specifically targeted at the lives of others. The life of the altar will depend on the sacrifice made at the altar, which in turn will summon particular evil spirits to attack a person. However, because spirits are not omnipresent, the practitioners of the evil altar will require something personal of the intended target such as a photo, fingernail clippings, worn clothing, hair, blood, etc. Such items, except a picture of the victim, carries the DNA of the victim so that spiritually the assigned evil spirits can locate their intended target in the spirit realm. This why it is so important to cover oneself and your loved ones daily with the whole armor of God and the blood of our Lord and Savior Jesus Christ! Now, when these evil workers of witchcraft can not retrieve such personal items of their victim. Then, through the consultation of the evil spirits from the altar, the witch or wizard would mix a concoction to either bury this evil on the intended victim's property or set it in a place where the victim will make some contact with this mixture. Other methods would be, placing it in the victim's food, drink clothing items or projecting evil spirits from the evil altars in the victim dreams. Therefore, dreams where one is always being fed or they're eating in their dreams, drinking in a dream, having sex in a dream or interacting with dead people in their dreams are all means of evil spirits being projected from demonic altars to begin the process of spiritually oppressing the life of the victim.
I am sure you've heard where someone was said to be "fixed" but it wasn't intended for them. In such a case, because the witch or wizard was unable to acquire anything personal of the intended victim. The witch or wizard made the decision to place it in the path they believe the intended victim would either travel. In another instance, spiritual concoctions can be put on food or drink items hoping that they would consume it. However, someone else consumed it or walked on it and as a result the person that have either walked on the concoction or consumed it. The concoction has now become the point of contact to begin the evil oppressive spiritual cycle of the system of witchcraft on that person.
The scriptures say, "Regard not them that have familiar spirits, neither seek after wizards to be "DEFILED" by them, for I am the Lord" Leviticus 19:31. The word defile in the above text means to corrupt or change the original of something. Therefore, the purpose of wizards and witches and their attempts to enslave their victims spiritually to the system of witchcraft is to change God's original intent for their lives. It is to ensure they become opposite to God's original purpose for them. According to Genesis 1:28, God original plan for man is for him to be fruitful, multiply and replenish. In other words, God always wanted people to advance in their earthly journey. Well, the system of witchcraft is designed to bring man's natural process of advancing in every area of his life to a slow and non-productive state.
