When roles in their Nativity are in dispute, the unaccountable aversions and antagonisms people have towards each other. Luminaries in dissociated signs or in inharmonious relation to each other are among the sources of such conflict; the Ascendants in opposition signs; the Infortunes in combination or in inharmonious aspect to the luminaries, or to each other or in opposition from angular Houses.

Sometimes loosely applied to planets viewed from an adverse angle of an inharmonious relationship, whereby they are deemed to bear an anipathy towards each other.
