As trite as it may seem, what I have found is a single yet complex emotion called love. It is undoubtedly the most attractive of all of Dr. Janov's books and contains twenty-seven interesting new case studies, two photographs, and numerous colored charts and graphs. For this reason, one should not expect that each of his books be radically different. Each of Janov's books is an interesting variation on this same primal theme.
New ideas mentioned in previous books become fleshed-out in subsequent writings.
For example, this work contains more information about the effects of electroshock therapy. In the section on depression, the useful effects of the newer anti-depressants are examined. A repeated theme through the book concerns the pernicious effects of oxygen deprivation in utero and during the birth process. Another expansion of an earlier concept, is Dr. Janov's development and refinement of his analysis of brain waves. He calls this procedure 'brain mapping' and believes that the use of brain maps makes it possible to diagnose and predict a patient's rate of progression in primal therapy.
