In seminars I provide the up-to-date knowledge about how we are built from the energy system point of view, how our consciousness, subconscious, superconscious and inner energy Source function. Nobody discusses the details of the human energy structure, because in fact nobody really knows them. It is the most important crux of the matter.
To be honest, nobody speaks unambiguously why our physical body suffers from diseases.
Medicine puts the blame for everything on external conditions, and in my opinion, their influence is marginal. When the spiritual and energetic nature of the human organism is ignored, it leads to total absurdities that I frequently notice.
Medicine has even its own branch of knowledge that shows to what extent the medical science does not know why things happen to people. It is called medical statistics.
