Born on the 18

A birth day above nine reduces to a single digit, and the older tables keep a character for the compound as well. The digit says which family; the compound says which member of it.

Born on the 18, you reduce to Nine and you are not only a Nine. The single digit is the family; the compound is the particular. Here it is conflict worked through rather than avoided. Two people who both reduce to Nine can arrive at it from very different directions, which is why the reduction alone rarely feels like enough.

Try this: write the problem in one sentence. If it needs two, it is two problems.
