In the first block, the twentieth arcanum turns the task away from the state and towards the lineage. The community a person answers to here is their own family and their own line, not the country at large.
This reads as a return to what belongs to the lineage: to those close to you holding together, to traditions and the settled way of life, to passing on what the ancestors have accumulated. Here too belongs an interest in one's own ancestry, which often wakes up on its own, with no outside prompting.
The system also links this arcanum to social turns towards insularity — periods when people draw back together into families and look outward less.
The arcanum is also responsible for what is inherited — for what passes down the line of the lineage and is not chosen by the person: the system places illnesses of the lineage and genetic ones here. This is its difficult side as well: the feeling that the family decides for you, and that stepping out of its script is harder than it looks.
