Anipathies

The unaccountable aversions and antagonisms people feel toward each other when positions in their Nativities are in conflict. Among the causes of such conflict are the luminaries in dissociate Signs, or in inharmonious aspect to one another; the Ascendants in opposition Signs; the Infortunes conjunct or in inharmonious aspect to the luminaries, or to each other, or in opposition from angular Houses. Sometimes loosely applied to planets seen in an inharmonious relationship through an adverse aspect, whereat they are considered to bear an anipathy to one another.
