That distinction between public, personal, and private space. We may view these as 3 distinct spheres that intersect like a venn diagram.

The public as ‘body’, personal as ‘mind', and private as ‘spirit' with the core connection being the ‘soul' as a manifestation of all. 

Soul is a much richer concept than Mind. Mind lost much of its ground thanks to modern day psychology as it evolved since William James in the 19th century.
