I was recently asked a question about Pluto aspecting Saturn in synastry, chart comparison. Since both are slower-moving outer planets I tend not to look to them as a primary focus. Their effects on each other are more generational. They move so slowly that a whole slew of people in that person’s age group would also share that aspect. What it does show would be the “generation gap.”
Saturn represents structure and one’s personal value structure is imprinted by the way one is brought up, where, when, and by whom. Pluto destroys what is no longer working and rebuilds. When one person’s structure is in hard aspect to another’s Destructatron (my own word; I just made that up) it may be that they attempt to destroy and remake your structure. This is particularly true when the two Saturns are in challenging aspect, or if there is a double whammy with Saturn and Pluto in interaspect; it’s mutual.
The reason behind this has to do with the generational divide. If you grew up in different cultures or decades you will have dissimilar structure. In easy aspect they may be compatible. In challenging aspect and when Pluto is involved this may trigger the sensors on the Pluto person’s Destructatron.
How strongly do you consider outer planet interaspects in synastry?
