Anything people don't know does not exist for them. Most people have no idea how many factors actually shape a human's mental functions already prenatal and the first 3-5 years. There is a genuine code in the cells of the brain that directs human development, which is based biologically and genetically on the polarity of male and female. Psychoanalysis teaches us that during the prenatal phase humans already begin to develop unconscious complexes, such as traumas and conflicts. The science of 'Epigenetics' teaches us that experiences such as war, violence, and scarcity are inherited from previous generations through chemical processes. Parental and cultural influences as well as environmental influences shape the mental functions of a person since prenatal und during the entire life. Brainwashing and propaganda, mass media, fabricated religion, standardized public education, economy, and so on, influence the mental development of people. Other aspects shape the psychological dimensions of male and female identity through gender roles, culture and individual characteristics. Already prenatally a fetus is exposed to contaminants, toxins, unhealthy nutrition, etc. Conclusion: Mental functions and life of humans are essentially programmed already during in the prenatal stage and the first 3 years. This book gives you an understanding about the factors that shape the development of humans, their behavior patterns and character and unveils the genuine path that allows for reshaping of the mental functions by respecting the archetypal code and capacity of each mental function.
