I really urge anyone thinking of self primal work to read my whole book slowly at least twice before attempting such a journey. The book is extremely simple and gives a very detailed view of the work. I urge you to find a therapist familiar with this type of therapy, and to also be in a group supportive of this work. I really don't understand how anyone can do this alone, but the fact remains that people talk about doing it all the time on the internet. The bottom line is that I don't know who will be successful at therapy and who will fail until I have watched them struggle with the instructions for several months.
Defenses are unconscious, most of the time.
Sometimes defenses allow you access and sometimes they don't. Sometimes defenses reassemble themselves, so you can get off the mat and function well and sometimes a person may become dysfunctional. Perhaps the most difficult part of all this is to understand that once a person's defenses are lowered, it can take many years to clear out the psychological traumas and pains stored underneath. A successful journey requires determination and focus, and acceptance of the process that is truly complete. Inevitably, self primaling is a big risk as is any depth therapy work.
