A Psychic medium has the ability to communicate with the dead or other immaterial entities. This has been practice even during the old civilizations they usually relay the messages through different means. Some psychic medium are said to have spirit guides who helps the medium to locate the spirits that they want to communicate with from the other side. They often uses different psychic senses. The Parapsychological Association explains that these senses into the following: Clairvoyance (the ability to see something through a psychic’s “mind’s eye”), Clairaudience (hearing the voice and thoughts of the spirit), Clairsentience (having a clear impression or sensation of what that the spirit wants to communicate), Clairsentinence (having the ability to sense the physical problem that the spirit had before death), Clairalience (being able to smell something that previously exist for example the spirit before loves to smoke a tobacco), clairgustance (the ability to taste an impression from the spirit) and claircognizance (to knowing it clearly through psychic senses).
Psychic mediums can experience a combination of these experiences while communicating with the spirits in a form of telepathy. Some mediums fall into a trance this is where the spirits uses the mediums mind to make a communication. During the 1860’s and 1870’s these types of medium were very popular and one trance medium named Leonora Piper was described by scholars in the history of Spiritualism. Some psychic mediums would experience physical mediumship it sometimes involves physical manifestation such as levitation, materialized spirit bodies, loud noises and moving objects much like those in the horror movies. The term direct voice is often used to say that the spirit is using the medium as a voice box to communicate.
On the later part of the 20th century, psychic medium had developed two ways to communicate with the spirits or channelling. The first one is known as clairvoyance where the psychic communicates what the spirit is communicating. The other one is known as trance where the spirit takes control of the body of the person to communicate. To make a better illustration of this you can read the story of King Saul, a Hebrew king who asks a witch to raised Samuel’s spirit from the dead. Seers those people who practices divination were present across every culture and history.
They often gives advice to Kings and was often asked in the past when to go to battle or not. There are many instances in the Bible where King David will go and ask for the Levite to ask for God’s guidance. The prophets also known as seers are filled with God’s spirit and they are commanded to give a message to Israel to repent from their sins. There are two types of seers mentioned in the Bible those who serve the true living God and does that serves other gods. Since God is a spirit and we should worship Him in spirit and in truth.
