Thank you Ilenak! This is interesting since I have SA Saturn square Venus exact in couple of months. And here we see Saturn to representing partner.
You are welcome.
SA Saturn to SA Venus may point to foundation or form being given to relationship. But by square, it may also point to obstruction or learning hard, important foundational lessons about relationships.
Remember, too, progressed aspects by transit or progression must be in the natal signature
to begin with in order to be realized. By that, I mean, for SA Saturn to meaningfully be expressed with SA Venus, there needs to be a relationship between them in the natal chart.
I think I have promising aspect for starting relationship at my solar return chart..but it seems there is yet stronger powers opposing it.
Of course, we are always free to think what we want.
PS. your notation SA means Solar Arc progression. Solar Return is SR.
