This is the kind of book that is very useful for group therapy or couples therapy. Has many experiential exercises. This kind of psychological material was very easy to find in the 1970's but now seems to be rare. I'm so glad I was able to find a copy in excellent shape.
I just wish more people nowadays were willing to explore these experiences. I used to do this kind of stuff every week in various different groups. I'm grateful that I was able to learn and grow as a result.
