A medium ( channel ) is a person who receives messages from supernatural beings such as angels, ghosts or deceased souls or who has other types of "non-physical" perceptions. In parapsychology, the term is used independently of culturally relative religious or occult worldviews.

One form of mediumship is clairvoyance , or "clear knowledge" is when you know something without reading it or being informed about it. In general, clairvoyance is a collective term that covers different forms of perception. These are also often referred to as supernatural. Strictly speaking, however, this term can only be used in connection with people who receive information in the form of visions. A person who is clairvoyant or has clairvoyant abilities receives images that are usually symbolic in nature.

Spiritual healing is an offer to those seeking help that stands on an equal footing with conventional medicine, naturopathy and other therapeutic offerings and is not in competition with them.

Spiritual healing activates the self-healing powers, promotes healing in a holistic sense, encourages and supports people in assuming their personal responsibility.

Mental and spiritual healing treatments can be used for any type of illness or disorder, for stress, and for physical and emotional injuries. They can complement other therapies or be practiced independently.

Neither anamnesis nor medical diagnosis are necessary for spiritual healing methods to be effective - the medically diagnosed type and severity of an illness is therefore not directly related to the outcome of the healing treatment.

Spiritual healing is based on a holistic view of the world and humanity, and therefore includes physical, psychological, mental and spiritual levels. Spiritual healing assumes that the world and every individual being is a soulful, complex, natural, energetic system that is influenced by a universal creative force/universal consciousness.
