This book refers to "New Medicine", which started in Germany with the oncologist Geerd Hamer and then expanded to many countries around the world.

Within the framework of this textbook, the principles on which "New Medicine" is based are mentioned, as well as the views it has on the doctor-patient relationship, its perception of illness, which is different from that of classical medicine, and generally its views on the connection of spirit (brain), body, and soul.

"New Medicine" is a holistic system because it considers the human being as a whole composed of body, soul, and spirit, which are inseparably connected to each other, resulting in direct influence. Thus, every negative psychological event is recorded in a specific area of the brain, which determines which part of the body will become ill because there, at the physical level, the psychological event will manifest itself.

Additionally, "New Medicine" can be combined with various symbolic forms (symbols), as well as with some divination systems and various energy protection measures, which, in combination with the understanding of the functioning of "New Medicine", can be significant aids in combating various diseases.

"New Medicine" can be correlated and combined with all the above, if and only if the therapist doctor can also deal with introspection, so that they can act both in the physical field and in the fields that are beyond science to help the patient who wishes to combat the disease that afflicts them in a non-invasive way.
