The culture has changed, the psyche has changed. There needs to be a form of introspective work that addresses our present-day needs. It turns out that spiritual completeness is simply getting back in our bodies. If we actually feel what we feel and sense what we sense, then the brain works fine, and all problems are solvable. The psyche is formed by imprints made in the earliest years of life.
Some imprints come from having one's defenses overwhelmed by experiences beyond their capacity.
These could be, for example, an unusually loud noise heard by the fetus two weeks before birth, a cold wet diaper unchanged for hours on a three-month old infant, fighting parents, absent parents, etc. etc. So, everybody has them. These imprints persist into adulthood and form a template for subsequent experiences. E.g., if I was traumatized by the sound of crying in the third trimester, I will tend to avoid exposure to crying in later life. I might even build a life-style around avoiding exposure to others' sadness.
