Anuradha and Dhanishta is the same

humourous generalization alert

Actually, the difference I see in the two is that Anuradha is Martian in behaviour, and Saturnian in values. It's the opposite for Dhanishta, which is Saturnian in behaviour, but Martian in ideals

They often dislike each other, because the nakshatras square each other, but they're the kind of vitriolic friends who would defend each other from unfair criticisms from other people.

They will dislike each other, because Anuradha is rash, does things without acting, is kind of cocky, and Dhanishta is a bit more aloof, doesn't engage in petty bullshit, and humble. Dhanishta thinks Anuradha is embarrassing

Anuradha sees Dhanishta as kind of succumbing to pressure that they should be avoiding. Dhanishta restrains itself (saturn) for the sake of gaining power (mars), and Anuradha doesn't respect raw power the way Dhanishta does. Anuradha finds Dhanishta equally embarrassing

But, really, Dhanishta wants what Anuradha has (strength and respect), and Anuradha wants what Dhanishta has (being humble and aloof). So, they'll always have that respect for each other
