8th house, inheritance, and rebirth
In my experience, the 8th house is of course a very private house that values sovereignty highly. But why is this? 8th house people seem to start in life more than others by inheriting, subconsciously*, t*he family dynamics and emotional complexes. This happens to everyone, obviously, but the 8th house's relationship to this fact is different somehow. Inheritance plays a large role in this house and it very much is psychic (in a literal psyche sense) contents from the family and immediate circle at the beginning of life. 8th house people are batteries that become filled with both negative and positive shadow aspects of their environment. The first "rebirth" is the flushing out of foreign influence, IMO. Its very much a house of merging, and this usually is automatic and to the detriment of the native. In other words, 8th house people need sovereignty so deeply becauee they can't help but automatically take on hidden and charged unconscious content. A big focus is on taking the first shadow shit of their life.
This is my working concept on this aspect of the 8th house, as someone with Sun + Moon and Uranus in this placement. Thoughts?
