During his creative life Oris has written about 100 books on spiritual-philosophical and esoteric topics, as well as on the mental and spiritual relationship between the human energy-structure and the energy-structure of the universe.A large part of Oris's life is devoted to spiritual work through writing books on cosmological subjects. In them the author uncovers such matters, which no one has ever touched so deeply and in such detail before. As early as 1996 Oris managed to find his Spiritual Mission, which he is tirelessly pursuing to the present day.
