Does karma, by definition, signal some sort of internecine conflict?

Yes, to a certain extent. Two competing issues, sometimes more, have to get resolved, be tempered in some respect, like metal in a forge. The combinations, analogous to the material used in swords, eventually make us stronger. Or you could see it as apothecaries do, creating an emulsion. When blending opposites, usually something good comes out of the mix. Karma is the ultimate blending, how the ALL makes itself more whole. Two warring parties coming to terms herald an incredible breakthrough: a newly-born stasis pregnant with possibilities.” ~ Rudolph Valentino
