Horizontal as referenced in the book is an esoteric concept that is parallel to concept of vertical in regard to human relations. The primary orientation in human relations is a vertical paradigm which is expressed in a hierarchal (vertical) relationship, and intrinsically unequal. On the other hand a horizontal paradigm in human relations has no vertical relationship orientation and operates with equanimity. The vertical paradigm orientation has predominated human relations and the imposed hierarchal scenario has become problematic. On the other hand the horizontal human relationship paradigm orientation does not appear as an option.
