Not all psychics are mediums, but all mediums are psychic. A psychic uses psychic skills to read the energies of people (spirits incarnate as human) within the earthly realm. A spiritual medium uses psychical skills to read the energies of spirits within the spirit world. A medium however, is psychic too and this can present a problem. When a client visits, you can pick up on their emotional energies, thoughts and expectations and this can effect the reading you give. You must learn to filter these out through practicing on many people first. You must learn through experience when you're picking up psychic energies or those of spirit. It's hard to describe skills such as these and they must learned within a mediumistic circle or similar group, explained shortly. Ask your client to close their eyes and relax for a few moments before you begin a session. Remind them to be free of expectations so that you do not pick up on them psychically.
Because the spirits who respond to the channelers are satanic, channeling is abhorrent to God. There are few who have any true conception of the deceptive power of spiritualism and the danger of coming under its influence. Many tamper with it merely to gratify their curiosity. They have no real faith in it and would be filled with horror at the thought of yielding themselves to the spirits' control. But they venture upon the forbidden ground, and the mighty destroyer exercises his power upon them against their will. Let them once be induced to submit their minds to his direction, and he holds them captive. It is impossible, in their own strength, to break away from the bewitching, alluring spell. Nothing but the power of God, granted in answer to the earnest prayer of faith, can deliver these ensnared souls.
They can’t interfere with the lessons you need to learn while you’re here. I remember a woman who was thrilled that her mother came through during our session. She wanted her mom to tell her if she should divorce her husband. Of course, the mother couldn’t make that decision for her because it wasn’t her job. The woman needed to take responsibility for her own life.
The Christian spiritual life is a journey that doesn’t exist in a vacuum. Christianity requires a community to exist in and teachers from whom to learn the faith, and features a cloud of witnesses cheering us on (Heb 12:1). The Holy Spirit animates the Church and, among other things, gives her the gifts of knowledge, wisdom, understanding, fortitude, good counsel, and fear of the Lord, piety. We have an obligation to build on those gifts sealed in us at our confirmation: and one of the most effective ways is spiritual reading. By reading good spiritual books, we can build on each of those seven gifts of the Holy Spirit. In addition, we can come to know the saints better, sit at their feet, and learn from their writings.
At some point, during one’s spiritual path, a conscious effort must be made to clear out the old karmic debts that still exist within our energetic field. In addition, the awakened individual will at some point begin to understand how they have created the negative karma and will learn how to stop creating anymore. If you can fully grasp the concept that you have lived numerous times before this one and that in order for you to even be looking at spiritual guidance as an option in your life right now, you will understand that you have had to experience many negative and probably despicable acts, both as the perpetrator and the victim. We cannot know the beauty and joy of our connection to the Divine without first knowing the opposite — Purgatory/Hell. If you can accept that you were once a bad person, capable of some of the worse acts of mankind, then you can learn to accept some of the negative stages of growth that you must go through in order to clear some of your karmic debts. The best way to get through these situations is to accept that you have responsibility for creating the negative situation you are currently involved in, maybe you are not conscious of the past events that led to the karmic debt, but learn to trust in the divine principles of the Universe.
The article about this phenomenon in Encyclopædia Britannica places emphasis that "… one by one spiritual mediums were convicted of fraud, sometimes using the tricks borrowed from scenic "magicians" to convince their paranormal abilities". In the article it is also noted that "… the opening of the wide ranging fraud happening on spiritualistic sessions caused serious damage to reputation of the movement of a Spiritualism and in the USA pushed it on the public periphery".
