My 40-year measurements of the aura with special patented super- sensitive equipment showed that it is nonlinear electromagnetic field (NEMF) - it is weak field, but it rules and regulates everything in the body, not with its strength but with the information it carries. I found that this NEMF is emotionally sensitive. When we experience positive emotions (or just think positively) the aura becomes brighter and we feel in high Spirit. When we experience negative emotions (or just think negatively) our aura is dimmer and we feel in low Spirit. Therefore, the aura we see in our emotional Spirit.
Now I am ready to answer the question: Why are we emotional? We are emotional because we are a material body and Emotional Spirit, which we see as aura. While our material body needs food to sustain its life, our Spirit gets its energy through positive emotions. It was experimentally found that positive emotions make our NEMF (seen as aura) to spin clockwise. Since the field is nonlinear, nonlinear physics apply, which says that vortices spin clockwise and suck energy. This explains the Spiritual uplift we feel when experiencing positive emotions.
However, since our Spirit is NEMF, there should be available NEMF energy out there from which our Spirit to suck when experiencing positive emotions. From here came the idea that there should be a Space Matrix (ether – see v. 1) from which our Spirit sucks NEMF energy at positive emotions. This answers the second question: Why Are We Craving Love? It is because Love is the best food for our Emotional Spirit.
