Summary: Neuroscience and psychology can be helpful to understanding our spiritual life.
After having read The Body Keeps Score on the science and psychology of Trauma, I wanted to read something similar from an explicitly Christian perspective and Anatomy of the Soul was recommended to me. (I also picked up This is Your Brain on Joy to read later.)
Part of the message of The Body Keeps Score is that our mental, spiritual, and emotional states impact our body and vice versa. The wholeness of our physical, emotional, and spiritual states matters. As Christians, especially as a Christian that is interested in the spiritual development of others, we need to think about how we can incorporate the knowledge of the physical into the practice of spiritual direction without attempting to be a psychologist or neurologist.
Anatomy of the Soul is broadly divided into two parts. The science and background about neurology, trauma, attachment, emotions, the prefrontal cortex, etc. and the shorter spiritual implications to our understanding of sin, repentance and forgiveness, and community.
