3in1 concepts is a special branch of kinesiology,  a very effective and powerful  complementary therapy which takes care the mind, the body and the spirit at the same time. 

Every symptom in the human body is caused by a stress-situation (a trauma, a bad experience or an unresolved conflict). When you are in a stress-situation, your energy system get injured. These injuries are blockages on meridians. (Meridians are channels through which life-energy flows.) Energy-blocks along the meridians could lead sickness and produce many physical and psychical symptoms.

If we treat the physical symptoms without considering the symptoms' psychical/spiritual background than this symptomatic treatment will not be successful. (Or there will be some remission but the symptom will reappear or strengthen again.)

When we take care the mind and spirit first, so we discover and resolve the Negative Emotional Stress, the energy system can get balanced. With this the body's self-healing process can start and work properly so the physical symptoms can disappear.
