In this book, we study the spirit and clearly define Physics and strictly spiritual interactions by means of (an extension of) the notion of free will. The basic physical principles of energy sensation (of the naked self, being immersed in society), feeding and sexual intercourse are discussed and precisely lead to electromagnetism and the dilaton, the weak interactions as well as the strong nuclear interactions respectively with its singlet, doublet or triplet representation,as well as the internal degrees of freedom being spin and color, charge, isocharge and hypercharge of precisely the particles of the super symmetric standard model. An explanation for the emergence of the proton and neutron is provided for as being the only stable compound particles which behave as fundamental particles in nature. Also, the psyche in the sense of Psychology and psychism is studied leading to predictions in medicine, sociology, biology and other fields of human be hehavior.
