Query: great textbook

Be forewarned, this is a textbook, not some easy-reading self-help book. The book explains that we erect defenses in relationships because of our mother, self-hate, and fear of death. It also explains how those defenses manifest themselves and how they are damaging to meaningful living. The book also relates how duality (saying one thing when we mean another) is damaging, in both adult relationships and with our children. There is a lot of explanation and insight here, but not a lot of direction for solving the problem.
